Tyler (Michael Trevino) seemingly finished things between he and Caroline (Candice Accola) when he walked away from her in Season 5, Episode 5 (“Monster’s Ball”) — but there is still so much between them left unsaid on The Vampire Diaries. Will these two have the chance for a post break-up debrief?

It looks like a Caroline/Tyler reunion will happen, if this on-set photo is anything to go by. In it, Candice, Ian Somerhalder (Damon), and Rick Cosnett (Dr. Wes) have their arms around one another, with Michael “photo bombing” in the background. Do these four have a scene together? We hope so — as unexpected as that would be.

So, why is Tyler returning to Mystic Falls? Has he officially given up on his mission of revenge against Big Bad Klaus (Joseph Morgan)? The TVDers hoofed it all the way over to The Originals to get Klaus back for the murder of his mother. And, he totally failed. The only reason he is still alive is because Klaus thought death would be showing mercy. And, we have a sneaking suspicion it might also be because Klaus knew how pissed Caroline would be if he killed her ex-boyfriend. But: how did Tyler escape The Garden?

If Tyler hasn’t forgotten revenge, then might he be hanging with Dr. Wes for some tips? The scientist has been researching on vampires for years. He might be Tyler’s only hope to effectively take down Klaus. Would the super serum Dr. Wes developed to turn make existing vamps hunger for vamp blood rather than human work on the Original hybrid? If not, would it work on Tyler? The serum makes vampire stronger. Would it make Tyler strong enough to take on Klaus? Because that would definitely make things interesting.

And how much of Tyler’s return is fueled by his desire to see Caroline again? Even though it would be mega-awkward and Caroline must still have some pent-up anger at Tyler, there’s got to be a part of him that still wants to see the woman he loves, right? Basically, we can’t wait to see what happens between these two unpredictable exes. Even if part of us thinks Caroline should stay single for a while.

Are you eager to see the Forwood reunion scene? How do you think Caroline will react? And why is Tyler back in Mystic Falls? Sound off in the comments below!

The Vampire Diaries airs Thursday nights at 8 p.m. ET on The CW.
