Daemon had a bastard, a daughter born from a whore pf the streets of Lys. He was informed it since her birth, and have been keeping a track on her, telling to himself that he’ll drag her out the brothel she was forced to work and live in, that Baela and Rhaena his daughters with Laena Velaryon, needed him more. And it seemed like they have spend 17 years needing him more, cause he completely forgot he had a daughter, a daughter of 17 years alone in Lys forced to sell her body to survive. One day he woke up and his guilt overpowered him, he flew to Lys in that same instant, no explanation to his new wife Rhaenyra, nor to his daughters, or step sons Jacaerys and Lucerys. He knew that if he didn’t do it at that moment, he would never do it.
