Chapter 3 is mainly going to take place in the TV dark world, with the "TV individual" being named "Anne Tenna" (from Spamton sweepstakes Tenna page.) I'm speculating that Tenna hurt Mike in the past, and Mike will be the CH3 boss. On to Chapter 4. I'm guessing that it will take place mainly in the Light World. There will be a Dark World, but it will probably be the shortest one so far, and the main boss might be named "Bishop." I do have a reason for thinking this will be the boss for CH4, though! According to Google, a Bishop is "a high-ranking member of the clergy in the church organization of many Christian denominations," so if that means that the boss will be named Bishop, the Dark World will take place in the church in Hometown. We know this because CH3 is on a Saturday, and people usually go to church on Sundays, so I'm guessing that Toriel will invite Susie to church with them. After the events of the Dark World, there will be a festival in Hometown. I think this because there is a song in one of the Newsletters named "Hometown Day." Everything next is just a guess based on absolutely no evidence. In the SnowGrave route, Hometown will take on an entirely new Light. Noelle will run away, and multiple search parties will set out to find her, completely changing the atmosphere of what was supposed to be a fun festival. Also, Asriel might return in Chapter 5, but that's mainly all I got for CH5. Though I do think that Chapters 5-7 are going to be less about new Dark Worlds and more about the story.

Thats all I got, thanks for reading!
