#Jay mertens seems like he could be an up & coming wizard. I hope Finn is okay though!

What changed Ice Prince Finn back to normal & where did he get a crown from?

Was Finn stealing a baby what ended up changing him as a person in the Farmworld universe? Similar to how Marceline kept Simon prime grounded & humane for a while.

Maybe Jay Mertens (I think that was his name, the eldest son) reminded him of his little brother too.

As for how the crown came back into the Farmworld reality, that would be because of whatever wacky effects are happening from Fionna & Cake going through the multiverse. Scarab was also messing with the multiversal TV's insides.

Going back to Farmworld Finn's little brother, maybe he was the one who broke the crown since I doubt a coward like the destiny gang leader would have been able to do it (or there's some sort of timeline loop going on with a bunch of the crowns that'll get shown later). This is assuming the little brother is alive, but we don't even know that for sure. There is just a lot we don't know.

edit: I see what y'all are saying about the old episode, seems like Prismo didn't wipe anyone's memories, he only made it so the crown would be destroyed. People still remember The Snow Man AKA Ice Prince Finn & what he did with all of that magical power. I also still think Jay Mertens could be the baby at the end of the flashback at the start of the episode.
