We can’t stop thinking about last night’s episode (Season 3, Episode 14: “She’s Better Now”) of Pretty Little Liars. And by that, we mean that we can’t stop thinking about that final scene between Jason (Drew Van Acker) and Mona (Janel Parrish). What was with his wound? We’re dying to know: Was Jason the one who tried to throw Aria (Lucy Hale) off the “A” train?

When we saw the small screwdriver-sized wound on Jason’s hip, our minds immediately jumped to the unthinkable. Was Jason the guy that Aria stabbed during the Halloween episode (Season 3, Episode 13: “This Is a Dark Ride”)? After all, he was on the train …

But then we calmed down and thought about the situation logically. Although it does make sense for Jason to be hanging out with Mona if he is working as manual labor for the “A” team, let’s look at the location of the wound one more time. Jason would’ve had to have been lying on top of the box in order for Aria to stab him in the same location of his wound. So either Jason is really bad at manual labor or he wasn’t the one Aria stabbed.

Other factors that point toward Jason’s innocence: 1) We’ve seen Jason shirtless, and we feel confident that Jason is strong enough to throw a box full of Garrett (Yani Gellman) and teeny tiny Aria off a train, and 2) Didn’t one of the Liars mention earlier in the episode that the stab wound should’ve healed by now? Did Jason’s wound look really fresh to anyone else? Could it be that Jason was the person on the skateboard and not Lucas (Brendan Robinson)?

That being said, we never saw the skateboarder fall on anything sharp. So could it be? Could Jason have tried to kill the girl he once kissed? We can't stop thinking: What object other than a screwdriver could've caused a wound like that?

Catch the next episode of Pretty Little Liars on Tuesday, January 15, 2013 at 8 p.m. ET/PT on ABC Family.
