The Mona connection. Why is Jason going around hugging Mona (Janel Parrish) and having her tend to his very suspicious injuries? He claims it's not because he's a bad guy, but come on. Anyone who's willing to hug Mona isn't entirely trustworthy.
The NAT club. As the Liars noticed after Garrett’s (Yani Gellman) murder, two out of the original three members of the NAT club have now been murdered: Garrett and Ian (Ryan Merriman). That leaves Jason. Is he in danger, too, or could he part of the plot against his former friend, in order to eliminate everyone else who knows about the group’s secret videos?
Jason disappeared around the same time Toby did. In the first half of Season 3, Jason was so fed up about Garrett’s impending release from jail that he got drunk and crashed his car. Toby (Keegan Allen) implicated himself to take the suspicion off of Jason, but what if it was just an elaborate plan for both of them to get out of town together? Toby didn’t show up again until the midseason finale, which was also when we found out he’s been on the “A” team this whole time. And Jason only resurfaced at the Halloween party. We could definitely see them both off somewhere (at that creepy motel with the “A” suite?) conspiring together.
He has motivation. Whether it's protecting NAT club secrets or avenging his sister's death, there are several reasons we can think of for Jason to be part of the "A" team. (On the other hand, he seemed genuinely upset when Alison's [Sasha Pieterse] body went missing...)
What do you think? Can you see Jason as evil, or do you think he's a good guy at heart?
