Pretty Little Liars Season 4, Episode 17 Sneak Peek: Andrew Is Back! (VIDEO)

Poor Andrew Campbell! In this sneak peek into Season 4, Episode 17 (“Bite Your Tongue”) of Pretty Little Liars, Spencer (Troian Bellisario) is getting her flirt on with her academic decathlon pal (again) in exchange for something she thinks he may have. What is Spencer after?

The 20-second video shows Spencer and Andrew hanging in her room, apparently under the guise of studying. Spencer, however, has other things on her mind.

“You’re starting forward and summa cum laude,” she tells her study buddy. “It’s time to share, Andrew. I’m not interested in your notes. I want some of your study aid — you know, the kind with the childproof cap. I need to stay up for awhile.”

Um, did Spencer just ask Andrew for drugs? It certainly seems so, and it lines up with the spoilers we garnered last year concerning the brainiac's imminent brush with narcotics.

According to E! Online, soon “Emily won't be the only Rosewood student with a history of popping pills.” Spencer, in an effort to live up to academic pressure while keeping her full-time hobby as an “A” hunter, will turn to pills to deal. And, though we don’t see Andrew react in the sneak peek, we don’t think he will be her source. According to the spoiler, Spencer will deal with Brenda, “an academic overachiever with a dirty little secret for her success.” So, we can only guess how Brandon will take in Spencer’s most recent bad decision — you may remember his strip trivia game with Spencer last season?

How do you think Brandon will react to Spencer’s request? And is Spencer about to head into another downward spiral? Share your theories in the comments below!
