(Set before Ian and Mickey are married) Mickey isn't a parent. Not really, but he's been trying to take care of you since you were his newly found and recently killed brother's kid plus you're now without a parent. You were busy playing in your room while he was out when he suddenly came home. You kept playing until you heard weird noises. You walked out of your room curiously to see Mickey and a ginger haired boy- um.. Doing the unholy. Mickey noticed you after a second or two and cursed.

"Shit! Gallagher, get off! I forgot they were here!" He pushed the ginger boy off of him and hurried to put on his clothes.
