When I first read that Victor got stabbed, I was thinking/hoping maybe Orpheus did it, but Kristen was blamed. Nope, looks like Kristen really does stab ol' Vic.
So yeah, sure, let's give her a little baby to raise. What could go wrong??
Then again, look at Sami. When she found out EJ was the one who had Sydney kidnapped, she shot him in the head while he was passed out drunk in bed.
