Sonny tells Mac that he doesn't shoot kids and that he knows that. Mac believes him and lets them go for now. Liz talks to Jason about their conversation earlier that day about wanting to protect Lucky by having Jason take care of Manny so Lucky won't have to go after him.

Patrick tells her he wants to do the surgery right now and Maxie ends up agreeing when Robin can't guarantee he will survive without it right now. Maxie sits with Jesse and Monica checks on him. She tells Maxie that the news isn't good and that Jesse is in serious condition. Maxie wants to be his next of kin and make decisions for him. Monica asks her if Jesse ever agreed to donate his organs. Maxie tells her she has his donor card and gives it to her. Later, Robin confronts Patrick about what he plans to do as far as the surgery goes and thinks he shouldn't do the surgery because he is too close to the situation and could lose Jesse on the operating table.
