Charles x Raven: A Thesis of the Mind

Charles is alone, back in his London mansion. One night, after many nights hoping, Raven comes to the surprise of Hank and Charles. (Of course they don't make out and whatnot that others would instantly assume.) Charles and Raven are back on track to being them against the world and knowing each other's thoughts without telepathy, even if that is just the start for them both.
