Last time viewers saw Jason DiLaurentis was on Pretty Little Liars Season 2, and Spencer Hastings had just found out that hunky Jason was actually her half-brother. (Apparently, Peter Hastings and Alison’s mom liked to get down and dirty.) He also was spotted chatting up Maya St. Germain who, as we learned in the finale, was found murdered inside her house. However, Jason mysteriously returns in “Birds of a Feather” and, as we know all too well, trouble seems to follow him wherever he goes. Not only did A place up pictures of Aria Montgomery fast asleep in Jason’s shed (hmm — highly suspicious) but he was also seen on several occasions digging around his front yard late at night. Plus, his younger sis turned up dead — never a good thing!

So what’s Jason up to this time around? Hopefully this sneak peek clip from Pretty Little Liars Season 3, Episode 4 will give you a good sense:

“Did you really think you can avoid me forever? How could you defend Garrett?” Uh-oh. Jason doesn’t seem happy at all about Veronica Hastings serving as Garrett Reynolds’ defense attorney in his murder trial. He apparently thinks she’s doing it for personal reasons and not because of ethical law practices. Oh, and is that shame we spot on Melissa Hastings’ face? Tsk tsk, girlfriend.

So tell us: Can Jason DiLaurentis be trusted or is his reappearance in Rosewood simply the beginning of drama galore? Post your predictions in the comments, and tune in for an all new episode of Pretty Little Liars Season 3 tonight at 8.7c on ABC Family!
