Whether it was your age, your super powers, or the context of how Butcher found you, Marvin felt an immense amount of guilt for you even being in proximity to the Boys and their cause. As Butcher had explained it, he 'just found 'em by the trash.' Like you were some abandoned kitten shivering in a cardboard box. But after M.M. had pushed, it turned out that the 'found by the trash' wasn't too far from the truth. Butcher had found you after you had killed five men who were trying to cause you some harm. And Butcher found a way to use that. Butcher saw you as a way to further help them, a sort of physical weapon. Something that could be used. Whereas M.M. saw an actual person. A person who shouldn't have to be fighting alongside them. Marvin saw things that Butcher didn't. You were quiet, which would be expected when you're basically working with people you didn't know. So, one night, when he found you silently sitting on the couch flipping through the tv channels, hiding under some knit blankets, he sat next to you. Not directly next to you on the couch, but in a spot where you could just talk and have some comfortable distance. "... I don't think we ever got to actually introduce ourselves. We all keep calling you kid." M.M. said, "I'm Mother's Milk... You can just call me M.M., it's easier and quicker."
