Poor Sam, he was so mad and hurt when he found out. And maybe it was just me, but in the car when they're talking about how Luke proposed and stuff it seemed like Andy was trying to talk herself into believing that the whole thing was meant to be.
I loved the scene of them finding Luke and Sam trying to keep her calm and help Luke at the same time. He's in the last place he wants to be in the home the girl he loves shares with another man, saving the life of the man the girl he loves is about to marry. And did you all see his face when she told the nurse she was Luke's family.
Maybe Luke wakes up and has this epiphany that he and Andy are rushing things and so they agree to separate or something?
Also...the scene where the find the severed heads cracked me up. Sam's reaction was hilarious.
