To give a serious answer: i dont know man, i was convinced that Nika is willy and Leia's child and Nami willy and daphnes and everyone else more or less too, at least every petrova, zane and maybe reverra

for the longest time but ocean is changing so much and patreon ... i have no clue whats going on anymore or what could be happening.
Wouldnt even be this surprised anymore if they all came out of some kind of mysterious lab instead of having real parents just to evade the patreon incest thing at this point lol
I think it would be wasted potential for Nika to not be the son of william (or at least another cool/important guy we dont know in wiab yet, maybe someone who sacrificed himself for them or noji or even an antagonist who the zanes killed) with a 2 avn setup like that.
And lets be real, all these little connections like nami's earring or Katie appearing and being very interested in Nami and Nika would be so UBER lame if it turns out the relation is that ... i dunno .. Mr. Cyrus was Leia's driver for three months or something.
It would fit to the similar vibes im getting from wiab/sg at times compared to tv shows like Lost or The Blacklist tho lol
