She couldn't have said what bird she'd imagined Damian was thinking of painting, but it sure as hell wouldn't have been a canary. She didn't realize that her jaw had gone somewhat slack either, and quickly picked it up, trying not to look as shocked as she felt. And that was just the surface emotion; there were others still, bubbling up deeper, something the felt a lot like acceptance and community at very least or even bigger like--
"You better check with Alfred before you start painting ceilings." She called to Dick, since the ceiling hadn't been primed or painted over yet, she didn't want to put any blemishes on the nearly two-hundred year old out-- and besides, it served as a nice, brief distraction from Damian so he wouldn't feel like she was turning it into a Thing.
She turned back to Damian and smiled, nodding her approval. "I think... I think a yellow canary would be just fine." She managed, thuogh she could feel her eyes getting misty (against her will, damnable hormones!). "Let me just see if we have other kinds of yellow in case you want some paint variety." She said to cover, carefully setting down her own paintbrush in the meantime and reaching for Bruce for him to give her a hand up.
Alfred would surely help find some other yellow paints-- and in the meantime Dinah could be excused until she got a hold of her self and didn't start sobbing or forcing bear hugs on Damian.
