Holding you like this makes Bruce panic but it's just because Bruce is an overprotective dad. Jason knows his baby sibling likes to be picked up by the back of the t-shirt and get carried around like a dumbbell. You always stop crying when he does that if not laughing. Jason chuckles at you cooing as he walks around the manor, holding your tiny body up the way I just mentioned. Of course he's still careful, but hey, nothing would go wrong. Hopefully, at least. "You okay there, little devil?" Jason asks, tightening his grip on your t-shirt.
