It would make me so happy if Cas could be in filler episodes.
I just think they’d get an extra dynamic from Cas being there. Cas showing off his knowledge of yoga, Cas going undercover and being either awful or amazing depending on the cover he’s given, Cas comforting victims by quietly listening to them and letting them grieve, then kicking ass when he finds the monster.
Just more Cas.
They’re here, now, in the bunker. Home.
—Best birthday ever.
Happy birthday, Dean Winchester.
This is not who I am…
