Kristoff (Scott Michael Foster) will continue to be a supportive fiancé to Anna (Elizabeth Lail) on ABC's Once Upon a Time as she gets involved with Rumplestiltskin (Robert Carlyle).

Foster spoke with TVGuide.com in a Thursday report, revealing that Kristoff continues to show faith in all of Anna's passions, especially helping her sister Elsa (Georgina Haig).

"I imagine the time you really want to prove yourself is right before a wedding. He has faith in her and wants to show that he can be a good husband," Foster said. "Kristoff and Anna just love each other. He just has complete support for his fiancée."

Continuing into Episode 4, titled The Apprentice, Anna enlists Rumplestiltskin to use his magic to help Elsa, though he reportedly has other plans for her. Kristoff will advise her on what needs to be done and what's best for her.

"You're going to see Kristoff again prove himself to Anna. He's going to have to give his own advice along the way about what to do," Foster continued.

Foster also teased a scene with Lail's Anna coming up that is filmed in a way that the actor has never done before.

"We got to do a pretty fun scene -- and I can't say what we're doing -- but I can tell you it's a bit out of the ordinary," Foster revealed. "It's a type of filming that I've never done before. It was fun to sort of be thrust into a new set experience that [neither] her nor I have ever done before. It was fun to actually do a scene that felt like we were doing a huge budget movie."

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