Fox says that in the episode titled "Half-Life and Havana Nights," Dr. Wick shows up to help Rosewood (Morris Chestnut) and Villa (Jaina Lee Ortiz) crack a tough case that leads them to Cuba. When they're stumped, TMI (Anne Konkle) recruits her old roommate, Dr. Wick (Gallow) to help untangle all the evidence.
Apparently this is the first of many more surprises to come from Bones. As the show begins its last season in January, Fox promises that the final 12 episodes will include even more unexpected turns -- including the return of fan favorites.
Fox has already featured one full-fledged crossover this season when New Girl traveled to New York and got mixed up with Brooklyn Nine-Nine. Bones also previously boarded the crossover trend when it joined forces with Sleepy Hollow last year.
Rosewood's "Half-Life and Havana Nights" airs Thursday, Dec. 1 at 8/7c on Fox; Bones' final season begins Tuesday, Jan. 3, at 9/8c on Fox.
