Everyone was in the wood trying to get to the very center, before they knew it bam they were they're a bill cipher appeared out of no where. 

Bill Cipher: we'll well, if it isn't the young pine tree, shooting star and Llama working together with the future. 

Bill laughs. 

Bill: now time to make a deal! 

Both Dippers: ugh! 

Bill: don't worry, it'll be fair. 

PDipper: unlikely. 

Bill: meh. Anyways It  very simple, give me pine tree and shooting star jr(referring to Antlia and Leo) , and I'll give your precious daughter back. 

FPacifica and FDipper: NEVER

Bill: fine, I guess I'll just have to send her to a different dimension! 

Bill opens up a portal and throws Bella in.

Everyone: NOO! 

Bill: good luck getting her back! Remember reality is an illusion the universe is a hologram buy gold bye!
