Pretty Little Liars dropped another huge twist on viewers on last night's Season 3, Episode 23: “I’m Your Puppet,” revealing that Spencer (Troian Bellisario) has joined the "A" team. What does the actress who brings Spencer to life have to say about that turn of events?

"Remember when I said I was A?" she tweeted, referring to comments she had made to that effect in the past. "...Remember all those times you thought I was joking?"

We must admit, she had us fooled!

What do you think of Spencer being on the "A" team? Do you think it's a great twist, or too much? Are you convinced Spencer is just doing it to take down the "A" team from the inside, or are you worried she's really gone bad?

Maybe the sneak peeks for Season 3, Episode 24: "A dAngerous gAme" will help you make up your mind. You can see Spencer come home, talk to her friends, and get cagey about who kidnapped Malcolm.

Catch the Season 3 finale on Tuesday, March 19, 2013 at 8 p.m. ET/PT on ABC Family.
