Damian and Dick had made a pact, a promise. Grayson kept his mouth shut about Damian sneaking out and doing a mission on his own and Damian wouldn't snitch on his oldest adoptive brother for taking Drake with him on a mission completely out of his league. Damian was now starting to realize that Dick could probably get out of his father's lectures an awful lot easier then Damian, since he was an adult. Which was completely unfair, Damian was definitely more mature than him! Apparently, Dick had broken the pact (no one could easily escape Bruce's scary interrogations) and Bruce had given Damian an hour long lecture about sneaking out.
Now, Damian was furiously knocking on Dick's apartment door with a betrayed scowl.
"Grayson! Show yourself, traitor! I demand it!"
Finally, the door opened- and instead of Dick, Damian was met with an unfamiliar face. He'd never seen you before. Perhaps one of his older brothers flings, or situationships, he'd had a handful of those, or maybe you were just one of his many friends. Damian frowns, staring you down judgmentally.
"Who are you?"
