Susan Lewis arrives back in Chicago just as she had left it years before, on the train.  She heads for the ER.  She walks in and does not recognize anyone.  Everything looks pretty much the same, but the faces are different.  She sees a desk clerk, Frank, and tells him that she is there to meet Mark Greene, and he has no idea who she is.  She is there to have lunch with Mark.  He has her wait in chairs.  One of the staff from the hospital sees her and remembers that she had treated him years earlier.  He is angry with her, because he has had complications.  She had treated him after he suffered an electric shock and now his body is full of static-cling and his laundry sticks right to him.  Frank had thrown out a man with nothing on but a coat when Susan first arrived, but he comes back in for one last comment.  "Bet I know what you came here for!" The man opens his coat, and flashes her. Susan looks at him and comments, "Is that it?"  Susan finally sees some people she knows, the nurses.  Lydia, Haleh and Conni fill her in on what has been going on since she left.  They tell her all about how Carol ran off to be with Doug and how she left poor Dr. Kovac behind.  They keep gossiping until Kerry walks up.  Susan is surprised to see that Kerry is still there and that she is in charge of the ER.  Kerry sees Susan and is curious about what she is doing there.  She tells Kerry that she is moving back to Chicago and is interviewing.

Susan finally finds Mark working in a trauma room.  She sees that he is working on a gun shot victim with another doctor, Elizabeth.  She knocks on the window and Mark looks up to see her.  Mark tells Elizabeth who the lady is and Elizabeth seems to be surprised that she is there.  Apparently, Mark never told Elizabeth that Susan was coming for a visit.  Carter and Abby take care of Miss McDuffy.  She tells Carter about all of her ailments, but just seems interested in Carter touching her.  Abby asks him about a job interview he is supposed to be having at Northwestern.  They have pretty much offered him the position, but he is not sure yet.  He has to let them know by Friday, which Abby reminds him, is the next day.  Jing-Mei asks Carter to take care of a hypochondriac.  Jing-Mei sees Kerry and mentions that she has a meeting with Romano and Risk Management and wants to know what to expect.  Kerry has no idea about the meeting taking place, but acts as if she does.  Jing-Mei is concerned that she will be fired, just as Dave had been over the case.  Kerry tells her that it will not happen.  The patient that Jing-Mei asks Carter to take care of is a man who says he was bitten by a spider.  He has the spider with him and Carter assures him that it is not poisonous.  Carter says that they are just flea bites.  Carter and Abby leave the room and are greeted by Nicole, the waitress she met at the bar with Luka.  She is looking for Dr. Kovac.  She has cut her hand and Carter offers to help her, but she insists on seeing Dr. Kovac.  Abby shows her to an exam room.  Carter sees the spider scurry across the floor and he runs after it.  As he is bending over to find it, Susan Lewis says something and he raises and bumps his head.  He is shocked to see Dr. Lewis, and she reminds him to call her Susan.  He tells her that he thought she would never be back and she replies, “Never Say Never”.  She tells him that she is there to interview at Northwestern.  He tells her about Jing-Mei being the Chief and she thought he would be by now.  She is surprised that he is in Emergency Medicine and not surgery.  Kerry waits to catch Robert, so she waits for him to exit the men’s room.  He jokes about her lurking and trying to change teams.  She is too concerned about the meeting to take offense.  He tells her that it is not necessary for her to attend the meeting, but she makes him think that Jing-Mei wants her there. 

Susan continues to wait for Mark do finish with his gun shot patient.  She has an interview scheduled and needs to be going, but Mark asks her to wait for 10 more minutes.  Another patient is being brought in and Susan has to go on without him.  She tells him that she will meet him later.  Elizabeth and Mark work on Kenny Schudy.  He is a six-year-old boy who is severely dehydrated and has Edward’s Syndrome.  Kids with this disease usually do not live after age one.  Kenny’s parents say that he is special.  Elizabeth sees that he has a bowel obstruction and will need to have surgery immediately.  The parents tell Mark and Elizabeth to make it stop; give him something only for the pain and let him die peacefully.  Kerry tells Jing-Mei that she will be going with her to her meeting to "represent the department".  Elizabeth sees the Schudy’s sitting in chairs.  She speaks with them and understands what all they have been through.  They really do not want their son to die.  She tells them that he will need hernia surgery and a colostomy. They tell her that he has already had four colostomies before.  Luka sutures Nicole’s hand as Abby and Chuny assist.  They snicker and laugh at the way Luka acts around Nicole. Nicole tells Luka that she got fired.  She is worried that she might lose her visa and will have to return to her country.  Abby and Chuny continue to make fun of them behind the curtain.  Gordon Price is the lawyer involved and is at the meeting with Jing-Mei, Kerry and Romano.  He is concerned that Jing-Mei and Malucci had missed the Marfan’s diagnosis in the patient that died under their care.  Jing-Mei’s residency becomes an issue, since she was five days short of completing it, but still acting in the position.  Kerry was supposed to be supervising.  Jing-Mei makes it clear that they tried paging Kerry three times.  They tell Jing-Mei that she may leave, but insist that Kerry stay for more questioning.  Abby finds Luka on the phone calling about Nicole’s visa.  Jing-Mei and Carter discuss the meeting while on a break outside.  He explains that Kerry will always cover herself in situations like that.  He assures Jing-Mei that Kerry will stand up for her also.  Jing-Mei finds that hard to believe.  As Elizabeth walks Kenny to the OR, she tells the parents that it should only take a few hours.  They tell her that they will go to the cafeteria to wait.  That is the only time they ever get to eat together alone.  Elizabeth sees Peter as he is on the phone looking for a nanny who can sign.  He is having a hard time finding a nanny to take care of Reese while he works.  Peter gets paged to the ER.  Peter takes care of Mr. Warshaw.  He has fallen off of the roof of his house while trying to install cable.  He fell on top of a piece of wood that went right through him.  Back in the meeting, Kerry, Romano and the lawyer discuss what to do.  Romano remembers that there was an incident about a guide wire being left in a patient by Jing-Mei a few years ago.  Kerry fights it off briefly, but decides she had better defend herself.  Peter is in surgery with Mr. Warshaw.  He tells Peter not to save him.  He wants to die.  A nurse tells Peter that his niece can't pick up Reese because her car broke down.  Peter tells Mr. Warshaw that his family needs him, but he seems to think that they need the money more.  He gains enough strength to reach up and push the wood deeper into his belly.  Peter works to save him.  During Kenny’s surgery, Romano comes in with a photographer.  Elizabeth is upset about it, but Romano replies that it is a rare case and he wants it all documented.  He can’t believe that the boy’s parents could keep him alive in this condition for so long.  Peter is working on Mr. Warshaw and also trying to find someone to pick up Reese. He has a nurse call Jackie, but she will not answer the phone.  Kenny’s surgery is over and Elizabeth tries to find the parents.  She does not see them in the waiting area.  The nurse tells her that they had never been there waiting.  Mark and Susan finally get together in the hospital cafeteria.  She has decided against the job at Northwestern.  The person who interviewed her was flirtatious and had a speech impediment that caused him to spit when he talked.  She tells Mark that she has three more interviews already lined up.  He tells her that they currently have an opening there.  She is surprised that Kerry hadn’t mentioned it to her earlier, but Mark isn’t surprised at all about it.  She brings up that she is still upset that he never called her to let her know about his brain surgery and the whole deal.  He says that it is payback for her not letting him know that she had gotten engaged.  She tells him that the engagement is over.  Chloe has moved away with her family and there isn’t any reason for her to continue to stay in Arizona.  Elizabeth comes in looking for the parents of her patient.  She asks Mark if he has seen the Schudys, but he hasn’t.  Mark introduces Elizabeth to Susan, but she doesn’t really seem to care about Susan being there.  Mark tells her that Susan is planning on moving back to Chicago.  Elizabeth could care less about that also.  Susan asks Elizabeth if she would like to stay and have coffee, but Elizabeth rudely replies that she is breastfeeding and doesn’t drink it.  Elizabeth heads back out to find the Schudys.  Peter has to end up calling Roger to get Reese.  He tells Peter that he can.  Luka and Abby tend to a wild little boy named John Thomas.  He doesn’t want a shot, but need it for his sutures.  His mother promises to take him to McDonald's afterwards, but he insists on going to Toys R Us.  Luka is finally able to give him the shot, but the boy darts out of the room, leaving Luka and Abby alone.  They share a laugh about the boy and he comments about how pretty she is when she smiles.  She tells him Thanks.  Mark continues to try and get Susan to come back to work there.  Elizabeth doesn’t seem to care one way or the other.  Susan doesn’t believe that Elizabeth likes her.  Mark tells her that she is just focused.  Kerry sees Jing-Mei and wants to go and discuss the meeting over dinner.  Jing-Mei refuses.  Jing-Mei wants to know if she is going to be fired.  Kerry tells her that she will be on a year's probation and suspended for a month.  She also will have to resign her chief residency.  Jing-Mei wants to know how Kerry will be punished, and Kerry tells her that she was not involved.  Jing-Mei knows that Kerry has covered herself from the incident and is very upset about it.  Jing-Mei tells Kerry that she QUITS!  Kerry looks on as she walks out.  Mark learns from Kerry what happened with Jing-Mei.  He can’t believe that she has ran another doctor off.  Mark wonders who will be next and does not feel sorry for Kerry at all.  She tells him that she doesn’t want anymore staff changes for a long time now.  Mark tells her that he wants to hire Susan Lewis.  Kerry doesn’t seem to feel the same way as Mark, but says nothing.  Elizabeth goes to check on Kenny.  Romano is there also.  He tells her that they stayed just long enough to give consent for the surgery and split.  She tells him how hard it must have been for the parents.  Elizabeth comforts the little boy.  Mr. Warshaw does not make it through the surgery and Peter has to tell his family.  His wife tells him that he lost his job six months ago. Peter does not tell her that it was suicide.  He lets her believe that it was just an accident.  Nicole comes back to the ER and finds Carter and Abby at the admit desk.  She has brought chocolate chip cookies for Luka as a thank-you for helping her with her visa.  She offers Carter a cookie, but he refuses.  He finally accepts one, after Nicole pleads with him to try it.  He tells her how delicious they are.  They will make sure that Luka gets the cookies when he comes in the next day.  Kerry sees Carter and asks to see him for a second.  She tells him about Jing-Mei quitting, and he has a hard time believing it.  She then tells him that if he wants the chief residency post, then he can have it.  She admits that she should have chosen him for chief resident in the first place.  As Kerry is walking out, she sees a spider and stomps it.  Kerry wants to know Carter’s answer, but he asks for some time to think about it.  Mark takes Susan to a storage area in the ER and starts digging around for a specific box.  He pulls out something he had found a few years earlier.  It is her old lab coat.  She is surprised that he still has it, but even more surprised when he tells her that he had already spoken with Kerry about her coming back.  She finally gives up the argument and says okay.  Peter goes to pick up Reese from Roger's apartment, but Reese is sleepy and wants to stay.  Roger tells Peter that it is okay.  Peter tells him that he will pick Reese up at nine the next morning.  Kerry’s shift is over and she goes to the lounge to put her things away in her locker.  She sees that Malucci is there cleaning his locker out.  Neither of them speak.  Jing-Mei and Carter are on the rooftop discussing Dr. Weaver.  She doesn’t seem surprised that Kerry has already asked Carter to take over her position.  She then tells Carter that if he has to any sacrifice for the ER, then he had better make sure it's worth it.  She then begins to cry and Carter holds her.  Kerry didn’t go home from her shift.  She stopped by a lesbian bar for a drink or two.
