•Rhaegal•

You fell to the ground abruptly without avoiding letting out a sharp cry of pain as you fell from your horse. You tried to get up when you saw how several archers were aiming at you, ready to kill you, but it was impossible, so you closed your eyes awaiting your fate. It was then that the dragon's wing covered you and then let out a loud roar and spit fire, incinerating everyone. He turned his head looking at you with concern and making sure you were okay. Daenerys noticed this while flying on Drogon's back and then seeing how Rhaegal burned everyone who approached to harm you made Drogon turn around to continue burning the traitors of the enemy army but then a smile formed on his lips as it seemed he found a new rider for his son

Rhaegal, since he saw you, you made his heart beat and soften and then he joined together so that no one would ever hurt you.
