condone
"No! For the last time, Jason, I cannot allow, nor will I condone this, this- whatever this is!" Bruce was near yelling already. It was a funny scene, but Tim, Dick, and Cass know better than to laugh, not when Bruce was so distressed over Jason being his "edgy teen" self.
"And you're not coming out of this house if you don't change out of that shirt, mister." Bruce lets out a heavy sigh, slumping against the back of the couch, watching Jason's face, sporting a smirk, with the matching teasing glint in his eyes.
Alfred comes in from the front door, pointing at the face of his pocket watch, with Damian at his heels. "We have to depart at once, Master Bruce. Master Jason can wear his coat over his shirt, we've honestly no time to dilly-dally. All of you! In the car at once!" He tells Dick and the others, who start snickering as they pass by Bruce.
"You heard the man, Bruce." Jason says, grabbing for his coat, which he left draping over the back of the sofa, just behind Bruce. "We're gonna be late to your own shindig," this is when Jason makes a run for the car, laughing in his steps.
Bruce will never understand his kids', especially Jason's humour. He'll just have to be careful of frowning too much, meaning he'd have to ignore his dumb sons all evening, so Jason wouldn't have to flash everyone his very misleading shirt.
