Where is Jack and what is he doing? Those are the two questions that have been looming large over Sam and Dean ever since the Nephilim left the bunker in episode 6. But in Supernatural‘s midseason finale, they finally track Jack down.

EW has an exclusive sneak peek at the episode, in which Jack is seen interacting with new character Kaia, and from the looks of it, she’s not a fan. Sam and Dean show up just as Kaia runs away, and they want answers. “I’m doing this for you,” Jack tells them. He explains that he left them to get a grip on his powers and to prove that he can do good, so, as he puts it, “I did the thing you wanted most.” What exactly that is and what Kaia has to do with it is yet to be seen, but we do know that she’s a dreamwalker, which could play into things.

Watch the full clip above.

Supernatural airs Thursdays at 8 p.m. ET on The CW.
