“Back in New York, whenever I needed to blow off some steam or force my mother’s hand, I’d go out on a bender, dancing with my fave celebrity gal pal, my best gay, and some dim-witted, sexy, disposable arm candy.”
You know what gets me. Robin was the name Dick's mom called him. The Robin colors are his family's colors. I like to think of Robin symbolizing a parents (particularly a mother's) love/protection that strengthened Dick. Now imagine Damian finding out that meaning and suddenly he realizes what Dick truly gave him, his family's love/protection. I imagine he'd be especially defensive/proud of Robin because Dick trusts him w/that privilege and how Dick wants him to feel a part of HIS family too.
