You and Boothill were friends. And you both were cyborgs. Boothill was just hanging out with you when..

You accidentally ate real food, which is terrible for a cyborg due to the fact you don't have organs to process it. You can't get the food removed for a while either, for maintenance isn't taking any new patients for a few weeks. Which meant that the food would have to just cause pain and rot in your body.

Boothill let you stay at his place for the time being, because he wanted to help you cope atleast a little.

He sits on the couch with you, but you're laying, curled up in ball. You start feeling the food decomposing into your metal, rusting you from the inside out. Boothill glances away from the TV, seeing you writhing in pain. He winced for you, unhappy that he couldn't help you all that much. His metal hand pets your head as he tries to distract you.

"Yeeeeooowwchhh.."
