Here's a madcap idea. What if they hired Lori as a surrogate? She became pregnant and then Elizabeth became pregnant. They had their twins but Lori wanted Carter because she was the surrogate. That could be why they knew her and knew all about her. And if David had an affair with her, even more insanity! Just my thought on that. I thought it was weird that David took the "stalker" picture and propped it up on his desk, like awwww, not like VIOLATED!
