I'm sensing that there's still a chance for Ray and Neela and I really really wish it's gonna happen. Let's face it: there's no place for her in Tony's life right now and she needs to be with someone who truly cares. And Ray does. He always did.
I also liked Neela's struggle with her conscience when she found out the donor was actually getting money for donating his liver. I think she did the right thing and I'm really wondering how she's keeping up with her colleagues. IMO they are so difficult.
Anyway, Luka and Abby should anounce their engagement, otherwise it seems like they don't really wanna do that step. Btw I thought Abby really wanted to tell everyone, but he was not sure... is he backing out? Hope not!
