The Molecule Man fell off my radar for a decade or so after the end of Secret Wars II. I guess I sort of assumed that he and Volcana were living happily ever after in a suburb of Denver and, well, good for them.
Then, he was part of the raft escapees in NA #1. Did we ever learn why or how he was arrested? Did he go back to a life of crime or was he just a continuity error?
Then he showed up in Dark Avengers, which I didn't read and was seemingly destroyed by the Sentry. Was he still evil?
If so, what caused him to turn evil? Did he and Volcana break-up? I see a reference on Wiki suggesting they did? What was it about (and how did he not destroy the universe in his rage)?
Any insight is appreciated as Marsha and Owie were one of my favorite Marvel couples.
