Forceful Drag: You move your speed. For each square you move, you slide a creature grabbed by you 1 square to a square adjacent to you. The creature remains grabbed, and you do not provoke an opportunity attack from the grabbed creature for this movement. At the end of the move, you can end the grab to knock the creature prone.
This power for the Fighter has no Target, as such, assume you have a creature grabbed in both hands. Can you:
A. Move Both creatures, as long as they remain within Reach (i.e. Sliding extra squares) during the movement
B. Choose only a single Creature Grabbed to move, dropping Grab on other creature.
