The honeymoon period is over, folks.

As seen in our exclusive sneak peek from this Sunday’s Once Upon a Time (ABC, 8/7c), Belle has need to confront the Snow Queen, but she’s not about to storm the icy lair alone.

Rather, she wants her powerful husband to come with — but will she go so far as to compel (or “compel,” seeing as she’s unwittingly brandishing a bogus dagger) the Dark One to do her bidding?

Elsewhere in the episode, in flashbacks Belle travels to Arendelle and, with Anna’s help, seeks out Grand Pabbie to help her regain lost memories and uncover the fate of her mother.
