Maisie Williams also said her character Arya is teaming with Sansa this season and they call out Jon:
"It's not often you see a character siding with Sansa who's not manipulating her, last season it was really tough for Sansa because Jon was thinking with his penis and it kind of made Sansa look bitter. This season you see Arya teaming with Sansa and sometimes calling out Jon. It felt nice and powerful to stand next to Sophie. Sophie and I are the tightest of friends when sitting across from anyone, so no acting required."
