Still pulling for preggers pegs!
I've read through a lot of the replies but I still think Pegs might be pregnant.
Agree that Saul and Lizzy could have done it, but there just wasn't a lot of opportunity in season 1 or 2. Also, with Lizzy being kidnapped, I'd give that baby a very slim chance for survival.
But I think Pegs' character could develop a lot from being pregnant. I didn't really like her from the start. She was weak, whiny, clingy and putting everyone in danger. When she killed Latch, it was a huge turning point for her. I think if Pegs had a baby to protect, she'd turn into a total badass in order to protect her unborn child.
Protecting Michael was her motivation for killing Latch, how much more would she do to protect a baby that belongs to her and Michael?
All I know is that I'm a family studies major and I freakin' love babies. Someone, anyone, better get pregnant this next season.
