Snow is being really annoyed in this promos. Though so is Emma.
I get it though, Snow knows how to handle herself in the EF, Emma on the other hand is completely out of her element. So she has to try and guide her very headstrong daughter who really isn’t used to having to rely on anyone so probably isn’t too receptive to listening to what Snow is saying. That 4th promo is very telling, Emma’s used to being in charge so she doesn’t really listen to Snow when she warns her that Cora’s dangerous at least not right away. I don’t think she’s gonna like taking Snow’s lead even though it’s what’s best and Snow knows this so it’s frustrating.
