"Alison's not the only one seeing ghosts tonight," Emily says in our exclusive clip. "Unless we're under a Bodysnatchers invasion, that's a real person." The first person who wants to confront the dark-haired Mrs. D-look-a-like? A seriously pissed off Caleb (Tyler Blackburn), who threatens to "beat the truth out of" Mary if he has to in order to get information about Hanna. (And the Haleb fans go wild! Don't worry, there's a tiny Spoby moment in the clip, too!)

So what happens when Toby (Keegan Allen) confronts Mary? And what's the first message A.D. sends to the group in the new season? Press play on the exclusive clip to find out.

In case you missed the PLL panel hosted by E! News on our Facebook page), the cast and bosses dropped some serious scoop on the new season, including that one of the Liars will be getting married (expect the proposal in the summer finale, and the wedding will occur in the winter), Spencer will end the season with either Toby or Caleb (and it made Troian cry!), and the gang will have "24 hours" to save Hanna (and they will go the "extremes" to do it.)

Pretty Little Liars' season seven premiere airs Tuesday, June 21 at 8 p.m. on Freeform.
