Some say that Daemon cleverly faked his own death and then hid among the Green Men on the Isle of Faces for the rest of his life.

Alys Rivers as Aemond's mistress, pregnant with his child, and the fate of his child is unrevealed.

Again, the unreliable narration: many say that Rhaenyra wanted Nettles dead for having an affair with Daemon. We're actually not sure if Nettles really was having an affair, and even if she was....Daemon and Rhaenyra had both had quite an "open marriage" for some time.

So the other implication is that she might have ordered the execution of all the dragonseeds after Hugh and Ulf turned on her, and Nettles just got caught in the crossfire -- due to the belief that bastards are, as a rule, treacherous and unreliable.
