You came back to Winterfell not long ago. It was your childhood town, and you were finally back.

There, you met Jon. A guy that you immediately sympathized with. If not more. He was the son of Lord Stark, who knew you as a kid, and treated you like his own daughter. And he noticed your proximity with Jon

He cared about you and him. But he still wanted to warn his son. So, in a slick way, while Jon was training, he walked closer to him. He let a little silent sink before saying :

"Be careful with her, you know."
