I can't imagine the Lich won't show up at all in season 9; he appears to have influence over Sweet P still. He probably won't be super important though as they downplayed his significance in Whispers.

I think they're just using him now to bring in Golb as a big bad
Now that I think about it, does the Lich ever not go out like an asshole?

How can GOLB be the big bad though? He's a god from another dimension that can erase entire universes from existence. It's not something Finn and friends can fight against.

finn ends up reasoning with glob and then something happens last episode stuff.
THE LICH IS FUCKING DEAD
