'I think it's probably one of the most interesting dynamics on the show,' Sophie Turner tells MTV News.

Ask any 21st century woman what she'd do to a fellow female who dare steal her fiancé and, well, the answer's probably not fit to print here. But in the world of Westeros imagined by author George R.R. Martin and brought to fantastical life on HBO's "Game of Thrones," the two ladies are apt to become allies.

Such is the case with Sansa Stark and Margaery Tyrell — the former, the once betrothed of boy king Joffrey, and the latter, the currently affianced. And while Sansa's undeniably better off without the maniacal monarch as a husband, it must be a bit awkward sleeping under the same castle roof as Joffrey and his new lady love.

Yet, as we saw in the preview following last week's season-three premiere, it seems Sansa will indeed find comfort with Margaery and her family as she waits to be smuggled out of King's Landing.

"I think it's probably one of the most interesting dynamics on the show," Sophie Turner, who plays Sansa, told MTV News recently. "You wouldn't expect it ... this sincere friendship they develop. Even though the Tyrells are, in a way, using Sansa, but also trying to protect her. I think it's difficult for Margaery because she acts like an older sister, but she knows the Tyrells might be using her. But their friendship is very sincere."

Meanwhile, Natalie Dormer, who plays Margaery, said that her biggest challenge this season is contending with Joffrey, she will also exert plenty of effort looking after Sansa.

"I think the dynamic between Margaery and Sansa is — Margaery is trying to be a bit of a big sister to Sansa. She wants to take her under her wing; she hasn't flipped her to the side and [is] expecting her to scrabble around on her own," Dormer explained. "The Tyrells want to take Sansa under their wing and adopt her and have her on their side."

And the consequence of all this on-screen affection? An off-screen friendship!

"I've had so much fun shooting with Sophie this season," Dormer added. "Two girls, together. We've been having a lot of fun becoming friends."
