If Dark Dan is the product of Vlad and Danny's ghosts merging, it means they have 2 kids?! Now it looks like Vlad and Danny divorced and divided kids: Dani stays with Danny and Dan stays with Vlad (too much 'danno' in their halfa family... maybe this Vlad's obsession over his lil badger was the reason of the divorce)
(lmao, Dani is elder, just like Jazz to Danny)
Someone who has never seen the show would laugh and say you're making this up, but the rest of us know... that's pretty much the canon truth.
Clockwork The courts ruled that Vlad has primary custody of Dan while Danny has primary custody of Danielle (though she informally emancipated herself from Vlad and is essentially Danny's relative now).
