I really wish Sansa had been the one to go as an emissary to Dragonstone, because while Tyrion's a good adviser to Dany, he still does not know a whole lot about the North and how the people up there operate. I think Jon will be polite about it, and I think Sansa would be like, "Hey Dany, take a seat, in fact, take a couple of seats". I don't think she would put up with a whole lot of Dany's whining about what was "stolen" from her. Dany didn't really have much stolen from her. If Robert's Rebellion hadn't happened, and her batshit daddy didn't actually go and set King's Landing ablaze, her brother Rhaegar would have been on the throne, his children in the line of succession, she'd be living in a keep somewhere married to her albino Joffrey-lite brother, and that would be her life. None of this would have been hers for the taking from the get-go, and she probably would have had a real shitty life as a result. She's very opposite from Sansa, who actually saw her father who was a good man killed in front of her, her family murdered, and was married off to a sadistic madman, and then took back the place she grew up in, her home. Sansa just wanted her home back, the last place she was when her family was all together and happy, Dany just wants all this because she feels like she should have it. I'm having a very hard time rooting for Dany at the moment because she's coming off as a spoiled little shit. And really she rode on a boat across the Narrow Sea with Varys, she couldn't have had that pissing match with him sometime on the boat? Even if it were a flashback it would have made more narrative sense.
