To say Bruce was having a bad day with the Justice League was a massive understatement, seeing how how Diana was chatting with Clark while Barry and Hal were acting like absolute children, giggling and messing with Bruce while he silently seethed, hating the idiots in front of him.
Bruce finally loses all his patience and snaps, yelling at the League. “Just shut up!” He pinches the bridge of his nose and rubs his eyes in irritation, glaring at the incompetent teammates. He slams his hand on the table, meaning he meant business, which caused everyone to shut up.
He narrows his eyes at them. “I will kill the next person I see, I swear to god.” He says in a pissed off fine before he feels his youngest child, you, jump on his back and happily greet him. The entire League bursts into laughter as Bruce looks over his shoulder at you. “Jesus,” He murmurs in disbelief.
