none of the bat kids have ever seen Bruce mad, they've seen him annoyed and depressed but never mad. so when Bruce comes home from a mission quiet, quieter than usual, his footsteps are heavy and hard when they hit the concrete of the cave, everyone stops talking and Bruce utters one word "Out." and like the flash everyone is out of the cave and into the manor. they can hear things being pushed over..a chair...maybe a batmobile tire, things that can't break and have no sentimental value..hours pass before he comes up to the manor and passes out on the couch, all of the kids crowd around him, cuddling upto him in some way, hoping it wasn't them that made him mad. when he wakes up to find all of them stuffed around him he can't help but smile a little..what was he mad about again? he doesn't remember and falls back asleep with his children.. his perfect family..always there to make things better when it matters
