[Reid probably could have stood in that door way silently for as long as he wanted. Helix was so lost in concentration he never even noticed the other in the corner of his vision. Normally his senses and paranoia wouldn't let him relax like that, but this was a thing he'd really wanted to do all on his own. It was a thing he taught himself and something many people seemed to enjoy. It was strange in and of itself, that he'd find himself wanting to play more and learn more for other people, doing things for others wasn't typically normal behavior for him. But he latched onto it none the less.
Reid's voice did reach him and his hands froze as he tensed, mostly out of surprise that someone was there at all. He relaxed slowly, hands moving to set in his lap as he turned his indigo eyes to the Agent.]
