These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
When Lenny brings Zoe chicken soup. And later, duck sauce.
When Coop's bride fails to show up for their wedding the rest of the staff are surprisingly sweet to him about it, despite the fact they never thought it was a good idea. Jackie even comforts him in her own way, and Eddie joins him for the 'carriage' ride home rather than let him go it alone.
Moral Event Horizon: May not fully cross it, but baiting your sponsor into joining you in rehab, getting her drunk after being sober for 10 years, then revealing that you signed HER into rehab to get her out of the way has to at least come damn close.
When Dr. Cruz is desperately trying to revive his son Charlie. Charlie dies no matter how hard he tries, and despite how much of an asshole Dr. Cruz has been, you can't help but feel sorry for him as he's crying and pounding on Charlie's chest.
Squick: It takes place in a Trauma Unit, so most every episode has a degree of this, however, a recent unexpected example would have been Thor removing his glass eye for Jackie. Somewhat more disconcerting when you realize this isn't special effects, either.
What an Idiot: Dr. Coop in regards to Dr. Roman. Dr. Roman has proven to be at least borderline incompetent, but, courtesy of an audio recorded liason with Coop, blackmails All Saints into letting her stay. Cut to the opening of Season 6, where Coop, while at least having the intelligence to know that he has to keep far and away from her, firmly believes that if she wasn't working with him would be a viable candidate for a relationship.
