And as they boned, Bran officially confirmed that Jon is, in fact, Aegon, the son of Rhaegar Targaryen and Lyanna Stark — aka heir to the Iron Throne ahead of his aunt/lover, Daenerys.
And, also while they boned, Tyrion lurked outside Dany's room and looked...well, none too pleased.
But why? Well, some think he might be going the way of Ser Jorah, and has fallen in love with his queen.
Others believe that he's worried about two rulers getting emotionally involved with each other mid-war. It could make for complicated alliances...though he seemed fine with it earlier in the season.
But the most convincing theory has to do with Tyrion's conversation with Cersei earlier in the episode. Remember, Cersei left the dragon pit and wouldn't call a truce with Dany after Jon refused to remain a neutral party in the war to come.
...so Tyrion went to try to reason with her. He entered a room alone with his crazy-ass sister.
Shockingly, he survived. And the last thing we saw of their conversation was Tyrion realizing his sister is pregnant.
Then, suddenly, we saw Cersei back in the dragon pit. And not only was she willing to call a truce, but she was also willing to fight alongside her enemies to defeat the dead.
Obviously Tyrion made some sort of deal with Cersei. The only question is: What kind of deal was it? What if Tyrion revealed to Cersei that Dany can't have children, and promised that her child would be heir to the Iron Throne after Dany's death?
It would make sense. Tyrion does seem to be genuinely racked with guilt about Tommen and Myrcella's deaths...
...and he recently brought up the matter of succession with Dany.
Perhaps this is the face of a man who's really worried his queen is about to conceive, which would throw a pretty big wrench in his deal with Cersei.
