Maybe there's still an egg somewhere. It would be fun if Sansa got it. 😉 Now two girls could fight.. 'No, my dragon is better!' 😉 Just an amusing thought...
I think she really cares for Jon and she's scared very much about him being killed in the South. Even now that she knows his her cousin not brother. She doesn't want to lose her family. And she's predicting, once again, that some lady is not fit for rulling... Also I think Sansa is scared about what happen after the war. If Cersei somehow win, she's fucked and the North with her (espacially now when Jon took all the remaining North army), if Dany wins, she's fucked and the North will never be independent and you can tell Dany will do whatever she can do get rid of Sansa as a person in charge in Winterfell and propably give that power to someone else who of curse would be gratefull for that forever.
She was really pathetic and desparate in that scene. I wish Jon wouldn't fall for it. He at least defended his family... a little bit.
Oh I like You already.
Sansa also pointed that out a little, when she told her, that the soldiers who need some rest are alse her people not only Sansa's or Jon's.
