Technically, the mission starts with a lot of really quick and quiet movement. The bang would come later. For now, stealth. Which is pretty damn easy when one's getting carted right on in by a speedster. They might as well be invisible.

Once inside, however, they have to move fast. Or, well, continue moving fast. But yeah, the whole supervillain league there contains a telepath. The stealth probably won't last long.

"Alright, Speedy Gonzales, do your shit," he whispered, and all around them things seemed to just...stop. The audience, the villains over on the set with their captives, everything.
