here is a new theory for you guys.

My theory is. When Michael and Kelly found Riley, and she was covered in vomit. What if it wasn't from all the booze she drank but morning sickness? Maybe Riley and Angel had a bit of fun that we don't know about before all hell broke loose. Now Lizzy isn't the only one that is with child.

Hmm, now that's a thought, I mean for riley to throw up from drinking I think i'd have to be alot, she seems to be what you would call a professional drinker, I suppose it's possible.
I do recall her saying, "Maybe I should have taken him up on his offer."

I'm not sure though.
