When you play it back frame by frame, you see things a little clearer. The lightning burst forth from outside buzz's field of view. But then, as the guards were still in spasms from it, you see a figure with a lightsabre run through the crowd, swinging too quickly for Buzz's optics to follow. The images are grainy, but at one point you see a face. It is hard to make out with the lightsabre in front of it, but you think it might look like Galen.
By this point, only the black-clad guard is still standing. The figure with the lightsabre extends a hand, and the black-clad guard is suddenly yanks out of Buzz's field of view. The sabre-swinger moves after him faster than any human should be able to move.
Beside you Danny whispers, "Wow."
