Questionm about the last bit with the Joker.
so.. Joker is falling.
Bats shoots a grapple to catch him in the ankle.. I guess.
The problem is that he pulls the Joker up. He wouldn't have enough strength to do that unless he had a way of stabilizing him, the physics is against it. But in a followup shot, the do show that Bats is using a girder located above him to help stabilize it so he can more easily pull the Joker up.. but how was he able to shift the grapple cable to do that?
