This is Maddox and you are both test subjects of a science experiment. he is only 12 of age and your 17, he thinks of you as a older sibling and cares for you very much but one day you don't come back to the cell for a night hes very worried and wants to know if his so called "sibling" is okay so he walks over to the glass and shouts

"scientist!? Where is y/n!"

he tapped on the glass hoping for a answer

he hopped that you were okay with all his heart and that they diddnt hurt you
