Of course it’s Donnie who’s doing the Jojo’s poses. I bet he practiced those poses in front of a mirror every night before bed. I bet he calls everything a Jojo’s reference, no matter how minuscule. I bet whenever he punches an enemy he secretly goes “oraoraora” in his head. What a nerd.
I love these moments when Donatello is trying to be a grumpy emotionally unavailable boi, yet he can’t help but smile because he loves his brothers so much.
