Kate turns out pregnant at the end and looks pretty sad about it...

admittedly, I was watching this while working so maybe I missed something, I looked up a wiki and it says Shane (her fake son) got her preggos...at what point did he impregnate her? I saw the scene where it seems, posing as Matt, he's about to rape her, but it didn't seem like he succeeded. Did I miss something?!?
