On board the Batplane…

Robin: -Tt-

Robin: All I needed was this aircraft, so why is it full of you idiots?

Red Robin: *locks the plane door behind him and sends his own jet back home via autopilot* I wasn’t gonna sit around the Batcave all by myself.

Nightwing: *lands gracefully from the ceiling and onto the captain’s seat* One of us needed multi-engine time for his pilot’s license.

Red Hood: *comes out of a crate and dusts off his jacket* And one of us would go pretty much anywhere to piss off your father.

Yup, it had nothing to do with them wanting to annoy you like good, loving, older brothers do.
