Yea, that teaser was pretty clear on where that relationship is headed, though it may take a little bit longer.
That was quite the episode for cameos and mentions of people seemingly long forgotten, with Miles showing up and Curtis, Chappele and Teri being brought up to set up the return of Aaron. It's too bad 24 doesn't have many living supporting characters, because it's always fun to see old ones turn up on a show that's gone this long. (Come to think of it, I think that's what people really wanted out of Milo's return. Not...whatever that was.)
Hey, if Tony gets to come back from the dead, can we get Nina too? That'd be peachy.
The fake out on the mole was well done, but I don't know that I care. I liked the twist with the backers better.
Dorne was already pretty relaxed about illegitimate children having official roles and being recognized, so for all we know, maybe Ellaria or one of the Snakes is now officially in charge of House Martell and is now Queen in the South?
