New Once Upon a Time cast member Elizabeth Lail recently spoke about her character Anna and how she will interact with the main characters of the show, including Rumplestiltskin (Robert Carlyle) and Belle (Emilie de Ravin) in the episode to come.

The next episode of Once Upon a Time, titled The Apprentice, features Anna seeking out Rumple in the Fairy Tale Land That Was in order to help find out what her elusive parents are up to. While he agrees to help her, it ultimately comes at a cost.

"She's on a mission to figure out what her parents were actually doing in the Enchanted Forest," Lail explained to IGN this week. "David's [Josh Dallas] mom points her towards [Rumplestiltskin]. She is not that afraid of him because she doesn't know anything about him and she goes to him and trusts him. He offers to help her and she trusts him. In the long run, he ends up manipulating her into doing something that she wouldn't normally do, because she's a good person and he's not a good person."

While it is not yet known exactly what Rumple will have Anna do, she at least becomes friends with Rumple's wife, Belle.

"Yeah, she makes friends with Belle. She goes on quite an adventure with Belle," Lail said. "We did a lot of hiking in heels that day."

Lail's Anna is one of many Frozen characters to invade Once Upon a Time in Season 4. Anna's sister Elsa (Georgina Haig), her fiancé Kristoff (Scott Michael Foster), the sociopathic Hans (Tyler Jacob Moore) and the reindeer Sven are also inhabiting the first half of the season.

Once Upon a Time airs Sundays at 8 p.m. ET/PT on ABC.
