Back in May, we reported that several Pretty Little Liars insiders were tweeting about Season 3, Episode 5: “That Girl is Poison,” noting that a big party was in store. Now, of course, we know that it’s Jenna’s (Tammin Sursok) birthday party. But we didn’t realize just how serious they were about the Mad Hatter theme until now.

E! reports that PLL will “introduce a young girl named Alice, who likes to dress like, you guess it, Alice in Wonderland! Creepy? Probably.”

Normally, we would expect this new Alice character to turn up a few episodes down the line, especially since it’s the first time we’re hearing of her. But is it? In those May tweets, PLL writer Bryan Holdman wrote, “Sneaky-peeky: Party on 305 set today. Wanna know who's birthday it is? Go ask Alice."

Does that mean we’ll be introduced to a “young girl” dressed as Alice in Wonderland in tonight’s episode (July 10)? How important will she be to the larger themes this season, including Maya’s murder and the “A” team?

Only a few more hours until we find out!
