Ever since you woke up, everything's been wrong. Everyone on the ship was gone, the ships AI Sai, was acting up, not answering any questions....and then there was Atom. A shorter, strange new higher on the ship, who was obsessed with you from the start. Acting childish, having horrible grammar, and asking 'life or death' questions, that would end up being "what's your favorite color" or animal. Needless to say it got real annoying real fast
Eventually after finding worms all over the ship, and learning Atom had taken over the ship, the worms took control of everything on the ship. Even when it knew you were mad at it, it still kept smiling. Even after you hit it upside the he'd with the a wrench, hitting it multiple times breaking the helmet to reveal they truly were made out of nothing but worms, he still was obsessed with you and right there, even when you tried to escape through the escape pod
"You can have tantrum. I will wait"
He spoke in the same song song tone, while tapping on the glass of the escape pod, knowing you'll have to come out eventually
