my take, it's esp if anything. that first tick was total bs, no way the vaga's on radar unless he has esp, and he goes straight to him. 31k is inconclusive in my book since he had a teammate on the other side of the doors, 70k again looks like esp but i think the best tick would be 15k. it's tough to tell with esp though and i'd like to have more ticks before a perma was made personally.
