Though Booth (David Boreanaz) and Brennan (Emily Deschanel) aren't too thrilled when Abbie (Nicole Beharie) and Ichabod (Tom Mison) show up at the Jeffersonian in the first hour of the Bones and Sleepy Hollow crossover, the duos do begin to find common ground as the case goes on.

Booth is automatically suspicious about Abbie's investigation into the newly-exhumed bones of General Howe and he doesn't hesitate to confront her about it in this exclusive sneak peek. But when Abbie admits she's attempting to solve an off-book case, Booth surprisingly has her back.

Watch their sweet interaction in the clip below.

The two-hour Bones and Sleepy Hollow crossover airs Thursday at 8/7c on Fox.
