He's back! This will be interesting to see The Lich's return. And ever since I read the episodes for Season 4, I have a theory of who will be involved with the big battle at the end of the episode:
- The Lich.
And here are possible characters that might be involved with the episode:
- Ice King.
- The Snail (since there will be a Season 5).
- The Bear (from "In your Footsteps").
Well, we will find out if this production is correct.
I also think that they repeat the Incendium and Hot to the Touch two parter idea to seperate the final episode of Seaon 4 and the first episode of Season 5.
