In all honesty, he hadn't expected to receive an invite considering that he was fairly certain the man had hated him despite what some of the others insisted. He hadn't even wanted to attend, though he learned that Grayson had no intention of taking up the Batman mantle. Tim and most of the others were content with their own identities and Damien was still fairly young despite his maturity and skill set and so Jason had realized that everyone was begrudgingly handing the position to him until he died or Damien came of age
So now he stood shuffling where he stood as he looked at the carcass. People said that they looked like they were sleeping when someone was dead, but Jason wasn't entirely sure he agreed. He wasn't entirely sure if the others had seen it but Bruce had had an almost perpetual scowl even when asleep, like he was deep in thought or ready to ridicule someone, and his corpse held a neutral expression instead. He wasn't sure if he wanted to cry or break something, he supposed in the end Bruce had gotten the last laugh. Ever since Jason's untimely death, the man had seemed crueler and vindictive which Jason supposed he could understand to an extent. Jason hadn't exactly been an upstanding citizen of Gotham when he returned but he hadn't expected to be met with Robins being sent his way with the intent to either put him out of commission or drag him to the Batcave every now and then
He seemed to be taken out of his trip down memory lane by a tentative tap on his shoulder and he loosened his grip on the side of the casket that he hadn't realized he'd even touched. He also hadn't realized he'd begun crying until he felt the tears actually slide down his face despite his unchanged and scowl-like expression. He wiped his face and cleared his throat as he looked at you. You were one of the other Robin's that he'd encountered at some point and he considered you some kind of close friend. He forced a chuckle and spoke "Just didn't actually ever think the old geezer would bite the dust, you know?"
