Regarding the sex theory....
Do you all think this could have happened b/w JR and LS? I just can't quite see that one. I mean, she hadn't been out with JR all evening. It was CR. So she has a kind of /sort of/maybe broken up boyfriend, then goes to party with a group of guys during the game (and the only girl, mind you), then goes out with CR, then puts him to bed, is turned down by MB from partying, then goes to have sex with JR? That would give me a who new impression of LS. I do not want to sound victim blaming, but there really area LOTS of girls like that, especially when they're on the "outs" with their BF. I just didn't want to think of her in that light....
So, that leads me back to CR. This would be a great "memory loss" excuse. So let's say she consoles him (which I've always thought she likely did, since he was hit in the head). It has never sat well with me that she just put him to bed, moved on to party with the room mate, then moved on to party with the next dude. So she consoles CR a little too much, has sex, and then ODs or dies from heart failure. Would MB and JR really accept the risk/lie for him? I don't care how good of friends you are, I just can't understand that. OK MAYBE his room mate, but JR too?
