Obviously this is Daenerys episode. Tyrion urges her to meet with Jon Snow, but I don't expect this meeting to go smoothly as she expects the King in the North to bow his knee to her. While we know Jon is a Targaryen no one else does so it'll be interesting to see how this meeting goes. If I have the lineage right Jon is her nephew.
