I like to believe Rhaegal was Baelor’s first baby because only they two inherited more of their Dornish side. So Baelor felt the need to protect him, knowing how it feels to not be ‘Targaryen’ enough. I love how though Rhaegal is mad, he is still equally beloved by his brothers.
Valarr and Matarys getting the silent, cold side of Baelor when they get in trouble while Dany can do whatever she wants without harsh repercussions because Baelor’s girl could never do any wrong in his eyes. Waiter, give me ten rounds of girl dad Baelor please
