She stays

"I'm sorry Jon. Arya has just got my dander up. She's always annoying me and doing things like this to show me up! With you, Robb, Mother and Father, not to mention around all the other boys!" She catches herself suddenly, realising what she's said.

You jump in with a reply as she moves to rush off. "I'll make sure I keep my eyes open and remain on the lookout for your things, sister."

You leave her to walk away as you prepare yourself for the day ahead, with a fresh confidence and some newfound knowledge. Sansa is looking for some male attention.
