I would be saying the same thing

*gets power to go invisible for the span of a single blink*
Well what the fuck am I supposed to do with this?

blink really really really really hard

Keep your eyes closed. Blink indefinitely.

It's someone else's blink. I don't know who's.

kill everyone 1 by 1 until you find the person that is blinking in line with your invis and kill them and stapple their dead eyes shut

Killing my source of power hardly seems productive here.

If they are dead and their eyes are stapled shut they will be forever blinking
