Where have you been, Mike Montgomery? Apparently, waiting for us in the fifth episode of Pretty Little Liars Season 4. That’s right! The baby Montgomery will be back this season, and now we have a confirmation of the exact moment it happens:

“Mike Montgomery is home. #405,” PLL showrunner Marlene King tweeted yesterday, and the whole Twitter-sphere rejoiced!

Okay...maybe not. Mike isn’t exactly the most riveting character in Rosewood, but he may be the most neglected. We’ve seen neither hide nor hair of Michael since Season 2 and we spent an entire Season 3 episode with Aria, locked inside the Montgomery house!

What will Mike be up to in Season 4? We have our guesses, but nothing solid yet. We do know that Season 4, Episode 5 is titled “Gamma Zeta Die,” lending our theory that Mike will be sneaking out (as he so often does) to engage in underage drinking and general bro-ey behavior at the same fraternity Ali got Cece kicked out of back in the day some credence.

Whatever Mike Montgomery is up to, we’re glad to know he’ll be back relatively soon, if only to figure out what the heck he’s been up to. Everyone’s a suspect in Rosewood! We don’t give passes to siblings of Liars (just ask Melissa).

Are you stoked to see Mike back on our television sets/laptop screens? What do you think he will be up to in Season 4? Let us know in the comments below!

Catch the next episode of Pretty Little Liars on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
