Pretty Little Liars Sneak Peek: Spencer Drops a Bomb Before Alison's Trial

Loading video...

The murder trial of the century is about to begin on Pretty Little Liars, but not before Spencer makes a last-ditch effort to set things right.

In TVLine’s exclusive sneak peek at Tuesday’s episode (ABC Family, 8/7c), the hasty Hastings confronts half-brother Jason and full-creeper Mr. DiLaurentis with proof of Alison’s innocence.

Unfortunately, as you’ll see in the above video, Ali’s dad isn’t exactly eager to make seemingly idle chit-chat with one of the girls he deems responsible for putting his daughter behind bars. Jason, on the other hand, might be willing to listen… if she can get past his guard dog.
