What if Voldemort had a son? Nephew? Grandson?
Would it even be possible for him to? He did become rather snakelike. I honestly don't remember enough of his backstory.
I just had a weird dream last night that made me think of this. And I'm still waking up, so sorry if I'm not making sense.
EDIT: Ew. I just did a brief Google search on "Voldemort's Son". Don't do it. So much "fan fiction" saying Harry was Voldemort's son or raised by Voldemort. And apparently there was someone in the Cursed Child whom people thought was Voldemort's son but wasn't; I haven't seen that play nor read the script, so I don't know.
