S15E17 "T-Minus 6"

This week: Carter has to make some adjustments as he settles back into the ER attending life, Banfield's husband sucker punches a guy, Sam's mom gets to Chicago but is far worse off than she realized, Brenner assaults Lucy's foster dad after the mere suggestion that he could possibly be a pedophile, Neela tells Dubenko some big news about her future, Morris is concerned about Claudia being hazed, and Frank has a very morbid sense of romance.
