"Right. Which light fits me best?" Doctor starts looking up and down the room, turning in circles. His feet catch on each other when he spins around quickly to try grabbing one of the lights and he trips, catching himself on his feet and righting himself just in time.

He straightens his jacket and sputters, "What's more difficult? Catching lights with the lights on or tripping in the dark following very visible lights?"

One of the sprites zooms past his face and he gives a shout and points. "That one! I think? Yes that one coming towards you now!" As Rei guessed, it was a bright blue light and it moved in tight circles and zig zags.
