Adrian has what he thought of as an epiphany and he draws on a notepad.
"Maybe the green coloration is something like making a neon light. When neon and argon gas are released into the light tube the initial electric charge creates the color." The theory was crude but it made sense to the soldier. He'd heard that there had been other gamma irradiated people and that one was gray. He'd also heard of the Abomination and the thought of fighting someone like that made him nervous.
