So I have to say I actually thought the scene with Daenerys and Jon at the end was fantastic. Daenerys pledged herself to help Jon fight the army of the dead without conditions, and Jon swore fealty to her. Daenerys' reaction to Jon calling her "my queen" was perhaps the most humble and vulnerable we have ever seen her, and her response of "I hope I deserve it" was great. Here is probably the most honorable and selfless person she has ever met, and he is telling her that he trusts and will follow her. She's not sure she even deserves that level of trust from someone like Jon, who she clearly thinks is better than her, but she's incredibly touched by it. Add to that the fact that both of them clearly love the other and the subtle hints towards a marriage alliance, and it was a great scene.
