Jason just grins. As he does, time slows down to a crawl. He won't run - after all, it's only running if you have both feet off the ground at the same time. Besides... for him, this is walking.
Walking at an "average" pace (for him) towards Merlin, faster than anyone in the room can comprehend, he spies the switch that would electrify the floor. He stopped for an atosecond to think. If he saved the team and got out of here, everyone else on the floor - Lux, the robot chief, Warlock, the millionaires - would all be dead. That would be some negativity it would be impossible for even Mordred to buy his way out of. There were enough straight media franchises around that it would get out. Chances are, the old man was bluffing, and wouldn't take that risk.
But to hell with it, he can't call Mordred's bluff and possibly let these people die.
Walking over to Merlin, he ties the wizard's arms behind his back, then hangs a bowl in front of the switch so that he couldn't reach it if he tried. He duct taped it down (always carry duct tape, kids) and then screwed it into the wall (always carry a screwdriver, kids) to make sure he couldn't just knock the bowl off the wall. That should do it.
Just to top it all off, he gagged the magician (see what I said about duct tape?) and grabbed Merlin's beer and took a drink, "So how's it hanging?"
