It wasn't his plan to get involved in the mess he was having between The Greens and The Blacks.

You were a Targaryen, and unfortunately you had been born at the time when Otto and Alicent wanted Aegon, son of Alicent and Viserys - Rhaenyra's father, to take the Iron Throne even after Viserys had made Rhaenyra his official heir. And to make your situation even worse, you were related to Alicent and Otto, which automatically made them think you were on their side in this battle.

Now, you were here, in the middle of the night resting with your daughters on the sand and the sea being illuminated by the moonlight in front of your eyes, trying to have at least a moment to clear your mind and relax a little, until two couples of cute footsteps on the sand were heard by you, unaware that both footsteps belonged to Daemon - who stood behind Rhaenyra like a guard - and Rhaenyra.
