[Sure, Leo noticed the bo, but he just assumed, with a year here, that Donnie made himself a new one. Or maybe it was even one he made with his powers that he's been carrying around. He was always attached to it, after all.

But Donnie stops in his tracks, insisting their timelines are different - not just that Leo arrived here a year in this planet's future, but... but what?

The big fight with Shredder, right! ...Except no, Leo and Splinter didn't go talk to Big Mama this last time, that was all the way back when...]

Wait, so... so you don't remember Gram-gram? Or Battle Nexus New York? Our second fight against the Shredder!?

[How far back does it go? How much does he not know about?]

What about getting arrested in the Hidden City? Mikey trying to make Draxum our second dad? April learning the Seven Deadly Vipers move!?
