Mark your calendars for July 23rd because whatever the Pretty Little Liars Powers That Be have planned for Season 4, Episode 7: “Crash and Burn, Girl,” it’s going to be epic. This according to not one, but two of the PLL cast and crew. Check out what Shay Mitchell (Emily) and writer Bryan Holdman had to tweet about the upcoming episode.

“And that's a wrap! You will not believe what happened! crAzy night... ! #16hrdayofdrama #PLL,” tweeted Shay in the wee hours of the morning.

“That? Was awesome! #PLL #407 #nospoilers #amazingpie,” Bryan shared late last night.

What is going to go down that is so awesome? Well, aside from the ominous episode title, we know that Season 4, Episode 7 will be a big one for Mike Montgomery, who makes his return to PLL two episodes prior. Could the craziness have something to do with our favorite neglected sibling?

Or maybe it has to do with the Toby/Caleb bromance happening in this episode? We saw them goofing off on-set in this Keek video, but things turned serious in this in-character screenshot that has Toby and Caleb engaging in some good old-fashioned computer sleuthing. Do they find something that leads to some sort of epic confrontation? Are one of our boys hurt (we’ll add Mike Montgomery to our official List of Concern)? Tell us your secrets, Episode 7!

Do you have any theories about what will go down in this apparently epic episode? Let us know in the comments below!

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
