The Black Sluggard

No, that makes perfect sense. That if Samson's desire to cut into skulls is genetic, then a love of pseudonyms might be, too. The skull-cutting-thing is a weird preference. Sylar is demonstrated as developing that entirely independently of his father and he gravitates to it despite his first kill being more of the skull-crushing variety, and he keeps at it even though he learns at least two different ways of getting abilities that don't require it (empathy and whatever he did to James Martin that didn't involve sawing open the skull). It wasn't *required* for the ability, but both father and son did it.
