Hmm... Not really sure how he was able to hear me, but fair enough - if the demo shows that, no complains. The way I saw it, a new person comes in, gets 3 headshots in a row and plays like a pro (Including when he was panorama'd, not only he didn't panic, he just 1 shotted the guy) and then when he noticed that people got suspicious, he toggled it off. I was afraid that it would be "inconclusive" just because he toggled it off completely after. Oh well.
It's just fun to note how well he plays when he joins and then suddenly he's just bad.
