There was so much to absorb from the season seven premiere of Game of Thrones, you might've missed a key moment: Sansa's hair. No, she didn't wear a killer accessory á la Daenerys Targaryen [1], but she instead hinted at a possible plot development with her half-up look.

In a scene where she warns Jon Snow about how dangerous Queen Cersei Lannister can be, he says, "You almost sound as if you admire her." Sansa replies, "I learned a great deal from her." Fittingly, Sansa's braided style seriously channeled Cersei Lannister's hair looks from earlier seasons, as several Twitter users noted:

Is it me, or Sansa's hair looks just like Cersei's some seasons ago?#GameOfThrones [2]

Sansa certainly "admires" Cersei. Sansa's hair this season matches Cersei from season 3. pic.twitter.com/fJmkhjgX4i [4]

That's super ironic that Jon said that Sansa must admire Cersei bc I was just saying to myself that her hair is serving Cersei szn 1 #GoTS7 [6]

Also, Sansa is really channeling early Cersei with her hair style. #GamesOfThrones [8]

This detail is subtle, but it could signal that Sansa wants more power and may be a threat to Jon Snow, the King in the North (and her half-brother . . . as far as she knows).

Sophie Turner herself has said her character's hair is a clever plot device [10]. "She's a very silent character . . . you don't really know what she's thinking," Sophie told POPSUGAR back in June. "The only real way we knew what she was taking in and learning from these people [is] because she would mirror Cersei's hairstyle or Margaery's hairstyle. . . . It's really interesting to see that sort of physical representation of her adapting to each situation."

If this Cersei-like hairstyle is any indication of how Sansa's storyline is going to this season, it looks like there'll be trouble in Winterfell.
