I think it was Mona... Because she was on the train after Jason paid someone to have Ali's body back, and the body magically appears on the train. So in my mind, it could be possible that before telling Jason where the body was, Mona forced him to help her pushing Aria and Garrett off the train. Jason didn't want to, he said it several times, and I don't know if he knew that the one inside the box was Aria. The next episode, 5x14, we see Jason and Mona acting like bestfriends, and Mona touching Jason's wound, that could be the one Aria did to her attacker with the screwdriver while she was inside the box.

Other not far-fetched combinations could be Lucas/Mona or CeCe/Jason.
