Why We Thought He Was "A":
- If Charles is at the center of this, his brother Jason might have a hand too. Regardless of whether Jason denies knowing Charles or denies his involvement, he could be lying.
- If there was anyone Mrs. DiLaurentis would want to protect the innocence of, it would be Jason. Plus, Mr. Hastings seems to be covering up that night too, and Jason is his son.
- Jason had been a part of the N.A.T. Club and had been in danger after Ali threatened to leak the videos she'd stolen.
- He doesn't remember the night Ali disappeared. There's even a point where he thinks he might have killed Ali.
Why We Figured He Wasn't "A":
- Um, remember when "A" drops Jason down an elevator shaft? Not really something you would want to inflict upon yourself.
- "A" has killed one other member of the N.A.T. Club. Jason may hate the girls and Ali, but he has no reason to want to kill Garrett.
