As we all know, the shift in world lines from the Berenstein universe to the Berenstain universe happened in early 2014. What other conspicuous event happened during that time?
That's right.
CHRIS-CHAN'S HOUSE BURNT DOWN
Now why would this be the trigger for the world line shift?
It's because Chris was meant to ==die== in that fire.
Burning to death from the clutter, along with all the sonichu crap he had accumulated over the years is nothing short of poetic, and is his rational end, but something or someone intervened and saved Chris.
Much like how Serge's survival created a new world line in the game "Chrono Cross", Chris inadvertently created a new world line when he survived the fire that should have killed him, in other words, he is dead in the Berenstein universe.
So does anybody have any theories about what interceded to save Chris from his fiery fate? I believe time travel may be involved.
