Dominic's smile grew when Parker took his hand, and he slowly led his roommate down the hall, away from the kitchen, towards his room. At the mention of the butterflies, Dominic stopped walking, holding out his other hand. He balled it into a fist, and when it opened again, a large blue butterfly was sitting on his palm, that he offered over to Parker.
"He'll stay with you, as long as you want." And it seemed true- despite the slight flutter of the butterfly's wings as Dom moved his hand, it didn't take off, as if stuck to him. The same would be true for Parker, if he took it.
