Once Upon a Time finale sneak peek: How will Regina react to Hook's return?

Now that Emma and Hook have been reunited, the Savior has the difficult task of revealing this new turn of events in the Once Upon a Time finale to Regina, who is still reeling in the wake of losing Robin. (More on that here.)

How will Regina — and the rest of Storybrooke, for that matter — feel about Hook’s return? Check out a sneak peek from the season finale, which also reveals the new threat the residents of Storybrooke will be facing.

The two-hour Once Upon a Time finale kicks off Sunday at 7 p.m. ET on ABC.
