The call is for an older woman with cancer and liver failure, whose family won't let her give up, even though she'd probably like to. They walk into her room and the woman throws her pudding all over Chloe's cheery scrubs because hospital food is terrible and depressing, and Chloe takes it well because she is relentlessly positive. We all hate people like this, which is why it's satisfying when Ronnie's ex-husband Mike rushes in with flowers and startles everyone and a bedpan full of urine ends up all over her. I wouldn't say it's funny, but I can't deny that it felt good to watch.
Mike and the Liver Failure Woman playfully charm each other a little bit, until Ronnie tries to kick him out for being ridiculously inappropriate at her workplace. He agrees to leave and she agrees to let him call her. Then he gives her the flowers and walks away and then for whatever reason she acts like he tricked her. It's weird, she starts kind of clucking words at him in a high-pitched voice like an indignant chicken.
Then we have an emergency. A gang shootout with the cops, to be exact. A kid with several critical gunshot wounds is wheeled in by Ronnie, Sonia and the male nurse (no one says his name! Ever!). He starts to code and a cute plain clothes officer standing around nearby starts freaking out and asking all sorts of questions and Sonia is like "I can tell you are a cop! Because I am Puerto Rican and it is a sixth sense I have!" Oh, how I wish I were joking. Anyway, the guy is a key witness, so the cop needs him alive.
Donut Doctor from before runs up to start working on the gunshot victim but freezes when Ronnie asks him if she should zap him with the paddles, so she takes the initiative and saves him. So every doctor in this hospital is incompetent, and all the nurses but Chloe are irreproachable pros? Sure.
Chloe is being shown around by an older nurse (played by awesome character actress Margo Martindale, who seems to work more often than any other actress in the entire world) and generally acting like overachieving obnoxious girl. They enter the room of a braindead patient and the older nurse flippantly tells her he's essentially dead, despite his heartbeat, so turn off all the machines keeping him alive and strip the bedding and then call the morgue. She hands her some paperwork and peaces out, and Chloe looks like she's going to throw up.
