[SPOILER] Plot Discussion Thread *Spoiler Alert*

[VaeVictis]

I think it was left deliberately vague whether Mandus is related to Alexander or Daniel, because both men have their own problems - why would Daniel take responsibility for Alexander's experiments? Why would Alexander be related to any humans?

Maybe Daniel, after some time in recuperation, returned to salvage whatever he could from Brennenburg? Or perhaps by 'experiments', Mandus was referring to the extraction of Vitae?

That's how I read it. I mean, no matter what ending from the TDD you go with, it seems to be a stretch of speculation to name either Daniel or Alexander as 'uncle.'
