Alison DiLaurentis (Sasha Pieterse) is finally back in action in Rosewood, and that means we have plenty of juicy scenes to look forward to in Season 5. Ali has a complicated history with just about everyone in Rosewood, with one big exception Caleb Rivers (Tyler Blackburn). But just because they haven't met before doesn't mean sparks won't fly when these two finally run into each other.

Caleb is returning to town in Season 5, Episode 5 (“Miss Me x 100”), and it won't take long for him to finally meet the legendary Ali. The writers say the result is a scene to remember, so when Wetpaint Entertainment caught up with Sasha Pieterse and Tyler Blackburn at the 100th episode celebration in Los Angeles, we obviously had to ask about this exciting encounter.

"Really the only person I haven’t had scenes with [in the past] is Tyler, who plays Caleb," Sasha told us. "And we now are introduced as characters and there’s one scene in particular that we’ve already shot and it's fun. It’s really fun, because he’s literally the only person that I haven’t filmed with."

Tyler got into a little more detail, dishing that we can expect a confrontation when these two determined characters come into contact.

"I think it’s interesting because Caleb really doesn’t put up with too much, so he doesn’t believe her, believe her story," he explained. "So he kind of corners her but she’s pretty fierce too and combats right back."

We can already see the sparks flying! Caleb has always been a no nonsense character, and according to Tyler he's going to be "definitely on a darker path and a little rebellious" after his return from Ravenswood (barely escaping a deadly curse will do that to you), so we're guessing he'll be more willing to call Ali out than almost anyone else.

What do you want to see when Ali and Caleb come face-to-face? Let us know in the comments below!
