Yesssss, and Sansa will respect the hell out of Ygritte's more obvious badassery. Plus I think it's probably safe to assume that she was keeping/planned to keep the North on good terms with the Free Folk? So there's that, too. :D

AW yes, Kat will absolutely older sister the hell out of her. She probably spends a fair amount of time around Marcus's, so they can hang out and bond and such.

That sounds good, yes! Zoe needs more friends too, especially ones who'd understand creepy supernatural shit.
