Pretty Little Liars100th episode is right around the corner — Season 5, Episode 5 — and we are gathering up every and all details about the milestone ep we can. For instance: it’s title. What do you call such an important installment? Check out the title for the 100th episode of Pretty Little Liars!

The episode is titled “Miss Me x 100,” as revealed by Tammin Sursok’s (Jenna Marshall) script for the episode. “Oh what's this?! Oh ya know... Just the 100th episode and #Jenna's return #PLL,” Tammin tweeted, along with a photo of the script in question. Yes, this means the blind-again mean girl will be back in the episode, which will hopefully bring back many a familiar face for the festivities.

What might the title mean? Well, the “x 100” is obviously as reference to the episode’s number, but whom are we meant to have missed? Ali will have presumably been back in Ravenswood for a few episodes at this point, right? Or will Pretty Little Liarshold off her return until the fifth episode of the season. That certainly would be epic: to spend the 100th episode watching all of the characters we know and love (or hate) react to Ali’s return.

Penned by showrunner Marlene King and set to be directed by Norman Buckley, the PLL Powers That Be are pulling out all of the stops for the episode. According to Marlene, “There will be a big reveal: One of our mysteries that we've had for a long time on the show will be revealed in the 100th." The episode will also include the return of Caleb from his ghost-hunting excursions in Ravenswood. How will Hanna react? Hard to say, but maybe that’s what she’ll be discussing with Spencer in the Spanna scene we know will be featured in the ep.

We may be psyched for a Spanna scene (always), but we have a very set list of scenes we need to see in the 100th episode, including a Rosewood get-together and plenty of Ali. Everything else is just icing on the 100th episode cake!
