Roach..

Walking around the base and going about your usual business, you notice a familiar figure sitting in the corner.

It was Roach. He sat alone and seemed preoccupied with himself.
As you get closer to him, you see him playing rock-paper-scissors with himself, and trying to somehow have fun while being alone.

Upon noticing you, his eyes seem to light up and he smiles brightly at you as a sign of greeting.
