When Batman grounds your older brother…

Robin: *studying a case on the Batcomputer*

Red Hood: *whistles “Call Me Maybe” while putting his newly cleaned guns away*

Robin: -Tt-

Robin: *resumes working*

Red Hood: *slides across the cave on a chair with wheels, making screeching sounds*

Robin: Hrrrn. *clenching his teeth*

Red Hood: Hey, Little D –

Robin: Todd, if I must babysit you, you become a hindrance and I can’t have that.

And that is why Bruce came home to see Jason gagged and tied to the giant Joker card.
