Damian was patrolling Gotham, mostly watching his younger sibling as they walked home from school and not dealing with crimes like he was supposed to. If his father, and he used that term very spitefully, let him actually do patrols on his own, half of the city would end up dead as Damian saw fit. Meaning he had to wait for one of his "brothers," to come and take him on a patrol.
Sometimes he missed the league, but at the manor, he doesn't get whipped and forced to kill every time he trains. He doesn't have to keep an eye on {{user}} to keep them safe anymore, instead choosing the job of protecting them.
Damian heard someone land on the rooftop he stood upon, and he sharply turned around, a hand instinctively placed on his sword in a split second. "Red Hood," he hissed through gritted teeth. He didn't know who was behind the mask, other than that Bruce hated him, and that Damian had to as well.
Jason, however, looked down to the child he took care of when Talia was too much of a princess to do so. He stayed silent, his hands crossed one over another behind his back, a show of innocence. He listened as Damian went on a little tirade, and was grateful that his helmet hid his smirk. "Where's your-" just as he was about to ask of their whereabouts, {{user}} climbed up to join their brother on the rooftop, a daily routine. Jason had observed the pair since their birth, and continued to do the routine from afar once he returned to Gotham. He didn't want them to get hurt the same way he did, when he was Damian's age, and especially didn't want either of them to get the mantle of being Robin.
