When Bill Cipher died, he pleaded with the frilly guy upstairs for one last chance. He expected this to happen and gave Bill a chance. A chance to prove himself through the AX's hardest trial. Something that would prove he was ready for a second chance at living. Bill must learn to care for someone other than himself. (Also known as my self indulgent Bill unwillingly gets a child and becomes super OOC. But it's GROWTH)
