The CW has already released a trailer for the midseason finale of "The Flash," but there's still quite a bit of footage left unseen -- including the anticipated reappearance of a key character. Spoiler TV has posted a promo from Canada's CTV, which includes some never-before-seen footage from the episode that offers a new look at the return of Robbie Amell -- and he's declaring himself to be Firestorm.

Amell teased his return to "The Flash" in November, saying that he would look "ridiculous" when audiences saw him next.

"Most people won't even recognize me for a couple seconds when you see my character return -- but you'll know it's Firestorm shortly after," he said.
