aside from the apparent/admitted bhop script it looks like he is using noflash. tic 51000 shows him throw a flash, he then does a faux turn away, gets flashed because it was a shitty throw, and proceeds to run in and head shot one player and proceeds to kill the other after flash fades. may or may not be noflash because it was only once instance but regardless the bhop script is enough.

edit: i started at ~35000 to start a round or two before the middle of the demo.
