We are introduced to Paige nearing the end of the first season when she is vying to be swim team captain vs. Emily. In episode 15, in a scene many tend to forget or disregard, she tries to DROWN Emily. That's right, drown. She holds her head underwater until Emily fights back and is able to resurface. Paige explains to Emily that she feels like she is trying to replace her on the team, but is that a real reason to attempt to kill someone? It's very hard to believe that this was so easily forgiven and they went on to date.

Anyways, now that we know Paige is fully capable of such a thing, let's talk about her and Mona's relationship. In the beginning of season 5, Mona decides to build an army against Alison. She recruits Paige, but Paige declines her offer...twice. After denying her a second time, Mona tells her, "You don't get to be some social Switzerland here. If you're not with me, you're against me." Paige was so fearful of Mona after this moment that she went to warn Emily that same night.

In episode 12 of season 5, Emily and Paige are decorating Emily's house for Christmas. Emily realizes she is missing one thing to finish the display, baby Jesus. She asks Paige and for some reason unknown, Paige has baby Jesus up on the balcony and throws him down to her. Watching it at the time, the scene seemed really strange and out of place. Now, it makes sense that they emphasized it. Here's why: when Mona is shown dead in the trunk of a car, baby Jesus is laying next to her. The reason is unknown, but the baby Jesus is the exact same one that Paige throws to Emily that day. Mona is also shown dead in the trunk of a blue car. Paige drives a blue car.

In episode 13, Paige suddenly has to leave town and move to California because her parents think it isn't safe in Rosewood. Even though it has been unsafe since season 1, the viewers have never seen or heard anything about her parents thinking this. Now, right after Mona is killed, she has to flee. Emily asks her to beg her parents to stay, but she seems more tenacious about it than anyone else. Could it be because she killed Mona? Or, is this theory reading too into little things?
