It's been awhile since "Teen Wolf" has spotted Colton Haynes and his character of Jackson Whittmore. The one-time kanima and current werewolf reportedly shipped off to London after the events of Season 2, and little has been heard from him since.

Thanks to photos posted by some of the show's current cast members, that has changed: Haynes visited the "Teen Wolf" set on Tuesday (May 20), and Tyler Hoechlin and Holland Roden posted the photos to prove it.

That looks ready to change in Season 4. Thanks to a photo posted to Instagram by "Teen Wolf" star Tyler Hoechlin on Tuesday (May 20), fans now know that Haynes has been spotted on the set of the MTV show.

Hoechlin's photo when up first, showing that Derek and his not-quite-protege were back together:



"Look who I found on the #TeenWolf set.. @coltonlhaynes," reads the caption.
Roden, who plays Jackson's ex-girlfriend Lydia on the show, posted a tender reunion picture:



Does this mean that Jackson is coming back to "Teen Wolf" in the upcoming season? Unfortunately, that would be a no -- MTV confirms that this was just a visit from an old friend. Fans can, however, hold onto hopes for the future.

Since leaving "Teen Wolf," Haynes has moved on to a regular role on "Arrow," where he plays the hero's protege, Roy Harper.

"Teen Wolf" Season 4 will premiere Monday, June 23 at 10 p.m. ET/PT on MTV.
