Well, that was fast! Just days after actor Brandon W. Jones mentioned he would be returning to Pretty Little Liars as Andrew Campbell, he is not only back in Rosewood, but hanging out in Spencer’s (Troian Bellisario) bedroom. You’ve gotta admire a boy with ambition...

Andrew, Spencer’s ex-decathlon teammate (and potential love interest), will be back in Season 4, Episode 16: the episode the PLL cast and crew is currently filming. Troian tweeted a pic of Brandon on the set of her character’s bedroom earlier today, along with the teasing descriptor: “Uh oh. What's @brandonwjones doing in Spencer's bedroom? #pll. #herecomestrouble.”

What does this mean for Spoby? Well, you may have noticed tensions rising between Toby and Spencer in this week’s ep (Season 4, Episode 10: “The Mirror Has Three Faces”) as Toby continues to ask Spence to lie to her friends about Toby’s search for his mother.

From this promo, it seems like the issue comes to a head in next week’s episode (Season 4, Episode 11: “Bring Down the Hoe”) when Toby accuses Spencer of choosing the Liars over him. Are Spencer and Toby going to break up? Is that why Spencer is hanging out with Andrew? Only time will tell. We like to think Spoby is endgame, but that doesn’t mean they can’t hit a few more bumps along the way...
