It was never outright said, but it looks like there wasn't any marigold kids in this timeline, hence why Hargreaves wife disguised as Tobias Funke set them on the path that leads to the marigold, them getting repowered and meeting jennifer, even though that doesn't make sense as a motivation, they had a universe with no marigold, the durango was safely contained, and then she empowers the umbrella's because this is her greatest sin?
But pretty much just chalk up to the general lack of care in the season, why did Luthor look huge again when that wasn't his power, that was something that happened later seperate to his powers, what was the point of everyone getting strange secondary powers when nothing comes of it (like what the hell is allisons new power, she rumours one guy just on eye contact, then is suddenly super strong, or can leivatate a guy, or burst that dudes nuts), , what was the point of reminding everyone that Viktor can pull marigold powers from people, make it a plot point for 4 episodes and then forget about it at the end when it could have actually been a thing, what was the point of Five and Lila having this 7 years separated from everyone else when they had no time to address it afterwards and do anything with it, which five left the journal our five found, it didn't lead him to the cafe so it wasn't for that, it was just false drama that he sat on it. Why is Sloan just never mentioned again, like even if they can't get the actress back, it should still be a luthor plot, and a hell of a lot better than Klaus and Thunderbolt , where does a giant squid with a child inside come from and why is it never mentioned again (I Figured when this started the secondary mutations where leading to something, like a stable time loop with Ben's mutation but no, nothing), and why does she come out of knowing the word cleanse besides for a suitably creepy episode opening? . And if it required all marigold kids to go into the cleanse, than what about all the alternate fives at the end?
And the worst of it. Hargreaves, after being an irredeemable ******* in all incarnations through the show, might be the only one who got his happy ending.
