While Thomas Wayne, the Flashpoint Batman, is visiting his son Bruce, the current Batman…

* Jason and Tim are both clutching a live grenade with the pin missing *

Dick: Grandpa, we have to call the League!

Thomas: No! No Justice League! *grabs and throws away Dick’s earpiece*

Thomas: There’s no reason to panic. 

Damian Yes, there is! You gave Todd a live grenade and he’s a total idiot!

Jason: He’s right, I am!
