I come to u with wisdom: Ivankov/Dragon/Crocodile. Iva was casually involved with the two of them, until Crocodile broke it off (over politics, I am sure they broke up over politics,imagine in the Crocodad scenario, Crocodile is screaming at Dragon about violent insurrection and military dictatorship four months into pregnancy and Dragon is shooting back stuff about the legitimacy of a dictatorship of the new world proletariat calmly, pissing Crocodile off even more. And Ivankov is in the middle of this, filing her nails and ignoring them). Iva is still tangentially involved with Dragon, but it's casual, y'know, just two adults fooling around. Iva also makes sure Crocodile stays out of sight out of mind for Dragon cause he always gets depressed about it.

Anyway, fast forward to today, Dragon gets news of Cross Guild, sees the other father of his child with Buggy the Clown and has a mini breakdown (Dragon must know Buggy, he is older than him and Roger and Garp were besties). Ivankov spends 4 days trying to get him out of his moping, then accidentally says something like "oh well, seems Croco-chan was waiting for a real clown to come along" and Dragon goes under again. Mihawk doesn't even register as a viable option, even though he is more than just a candidate, because Crocodile was always into high maintenance losers and Buggy fits the bill to a T (as does Dragon. And also Mihawk. And Doflamingo. Ivankov was the only exception to this rule.)

TLDR Cross Guild announcement jealousy but from Dragon this time, we're giving Shanks a break.

YESYES I absolutely adore this. It's canon to me. I know they have something going on.... I know....
