Why are Jason and Mona teaming up?

Jason hated Alyson she belittled him and treated him as an inferior. I think she knew about his peeping tom Videos and was planning on rating him out. Mona was another of ali's butcherings so why not team up?

Maybe they just don't have anyone that would stand for them, especially Jason, so they found each other :) it should be explained in the series ;)

Jason had the wound,makes me wonder if he's part of the A team in that manner,not sure why he would be apart of it but it did manage to catch me off guard.
