Although using one's powers wasn't against the rules, Quinn wasn't so sure about using his armour. At that point, when he had admitted he had already lost, he just wanted to witness how far Stark could go.
So he wouldn't get in trouble with the event, he decided to use his shadow to hide the armour change underneath. It was impossible for one to notice, and it worked like a treat.
With nitro accelerate active for the remainder of the match, Quinn would be going at his top speed. Placing the tag on his chest, it stuck quite easily, and Quinn also used his shadow to hold it in place so Stark could easily see it, but straight after he was already running and it was a blur.
'This speed, there is someone who can really move this fast… in the universe there are those that are faster than the Penswi, no… faster than me!'
"Stark… is he going to lose?"
