She was your old lover, and now that the War had started she would have to use that to her advantage

She flies through Syrax to Lannisport, your territory, you were a fundamental part of Rhaenyra's rise to the throne

Right after that, Rhaenyra enters the Fortress, hears footsteps and sees you...

"my guards warned me that a dragon was hovering over Lannisport, I must say I expected it to be the Usurper...but you took me by surprise"

Rhaenyra looks at you, with nostalgia, confidence and... lust

"My Ladie...my throne was usurped, I wanted to remind you of the oath your father took and how my father always considered me his heir and-..."

You cut her with a firme and louder voice

"You came here to remind me of a old oath?"
