Carla: You two are so boring.
Janitor: Janitors aren't boring.
Carla: You wanna know the weird defect you both have that made you screw up like this?
Elliot: Please.
Carla: You're both humans.
Janitor: Janitors aren't human.
Carla: They are! And Elliot, I'm really annoyed with you because I gave you this lecture two weeks ago.
[flashback:]
Carla: Pay attention, because I don't wanna be saying the same thing again in two weeks. You're both human.
[present:]
Elliot: I don't recall that.
Carla: It's human who want the best for your patient, even if you can't follow your own advice. It's human to get passionate about something and then get complacent. It's annoying to whine about it all the time!
