Quartet of Misfits

Abandoned, forgotten, bullied and lost. That's pretty much what they are. Harry's abandoned by the Dursleys. Ron is forgotten and accidentally left behind in London. Hermione is bullied and ends up on a random train. Draco loses his memory and is lost in the Muggle world. They don't seem to be able to fit in anywhere. They were Misfits. But maybe, just maybe, they fit together.
