Franco: Long before we knew Franco (played by Oscar nominee James Franco....where'd they get that name from?) was Jason's secret twin, we at least knew Franco was crazy. An eccentric artist, Franco had a dark obsession with Jason from the very start, and his initial targets in Port Charles -- Carly, Sam -- only served as ways to get closer to Jason. After a series of standoffs and returns, Franco stalked Jason and Sam on their honeymoon, and in a horrifying moment, he drugged and raped Sam. Jason got his revenge by killing Franco, but the rape, and the paternity doubts it raised, ended up helping to destroy Jason and Sam's marriage.
