Actually, I'm still on the fence about her bleeding in her house. I know I said "pj
s with blood"..but it was just for id purposes. Which day was the blood on handrail discussed? If any one can remember, I'll gladly go look-see what was said.
Here's a theory that makes sense...
Someone from Dad's, who was invited back to the house to "party", showed up just after the pizza people left.
Damon/Brenda/3rd person "swing" in MB and fall asleep after the "session".
3rd person wakes and takes Danielle.
Mystery solved.
