We knew that Mike Montgomery (Cody Allen Christian) was making his long-awaited return to Rosewood in Season 4, but now there’s photographic evidence! Holly Marie-Combs (Ella Montgomery) tweeted this adorable picture of the on-screen mother/son duo on set. (Disclaimer: this photo will make you smile.)

“Oh. Look who I found,” Holly tweeted along with the pic. Mike was gone for the entire third season, so we can imagine Ella’s surprise in running into her son around the house. It’s also nice to see these two so friendly (even if it is behind-the-scenes) considering Ella and Mike hit such a rough patch in Season 2 when Mike spiraled into depression and accidentally injured Ella’s wrist.

What has Mike been up to since we last saw him? We have a few theories. Whatever trouble he’s found, he looks good. Mike Montgomery is all grown up now and ready to give some of the other Rosewood hotties a run for their money. Hanna dated Mike in the PLL book series. We wonder if she will take notice?

We’re getting Mike back for not one, but at least two episodes! He makes his return in Season 4, Episode 5: “Gamma Zeta Die,” but Season 4, Episode 7 seems to be the episode Mike Montgomery fans should really be getting excited about: “And all you @ReallyCody fans should gird your loins. #PLL 407 will (hopefully) not disappoint!” PLL writer Bryan Holdman tweeted last week.

Are you glad to see Mike again and in scenes with Ella? Let us know in the comments below!
