Imagine if Jason had been A, and he was like, “I’m not even Jason. This is Jason,” and held up a picture of Jason from season 1. “I killed him and stole his identity and you people didn’t even notice.”
And then every PLL fan in the world would lose their mind screaming that they had noticed, but they didn’t think it was an actual clue.
Seriously. It would feel exactly how the actual reveal did, but at least it would have been fucking hilarious.
