But I have a weird question (don't question it): Would this scenario technically be incest if Weather is kind of F.F's uncle...(?)

So what if some sick bastard (Araki) made this ship a thing?

A. it isn't f*cked up because Whitesnake just made the plankton sentient via it's ability, therefore it doesn't count.

B. it is f*cked up due to Pucci and Whitesnake being the ones who "raised" and gave F.F her sentience in some weird Frankenstein's monster logic, therefore he technically adopted her.

C. "Where tf have you been Vibin, it's been a year and 8 months".

D. All of the above.
