Roach is great at scaring the sh*t out of you, not on purpose, but every time he does something just happen to be nearby.

You're walking down the storage room after Price sent you to get equipment. It's a eery place that already gives you shivers when suddenly you hear a small piece of metal fall from the roof.. you look up, and Roach is hanging on the top of a pipe. You're speechless, and before you can say anything, he interrupts

"No questions till I'm safe on the ground!!"
