The birdarang is in Dick's hand in a flash of red and he's gesturing with the other for Blake to drop back. After all, he's not sure what the range will be of the explosives in this one, and he'd rather not be responsible for someone's death so soon in a new world.

The red device shoots out of Dick's hand and gets embedded in the base of the scorpion's tail, the little lights flashing with the tell-tale beeping of a bomb. Then Dick's shooting at the scorpion with the handgun, counting bullets in his head as he tries to keep the beast distracted from attacking Blake more until the bomb goes off.
