It's hard not to smile at the way Jon's face lights up, especially since Robb has said several times how broody and serious he usually was, although it doesn't stay on her lips for long. Robb's mentioned you. Merely mentioned, of course. In his grief? Who's to say?

"Aye. It has been..." She looks around uneasily. "So strange." Between dying and waking up in a foreign place and having to forcibly come to terms with what she's lost, and then that episode in the tavern and meeting Robb here... "I am rather overwhelmed, and I do not know what to do or where to go. But it is a pleasure to meet you at last, Jon."
