Gerard- what else? Your guy's ideal quality time was cuddled up together reading comic books, telling each other funny parts that would happen every now and then.
Mikey- you would usually just lay in bed listening instently to mikey play his guitar.
Frank- you guys would usually enjoy watching the walking dead or a show/movie about some unsettling and cuddling up on the couch with snacks as you watched
Ray- you two would sometimes just never leave the bed and just stay cuddling, talking quietly as though other people where in the house and you didn't want to wake them.
