"Changed the rules? How? The only original reason why I could travel through is because of the jewel. I can't remember how Inuyasha was able to trace through but anyone else should've gotten stuck or just fell to the bottom.", Kagome says.<br/><br/><br/>"What rule could've it changed?", Shippo wonders<br/><br/>They thought until Kagome speaks up , "It was never sealed..."<br/><br/>They look at her and she continued with, "Before I came to the era, the well on my end was sealed. It's the same well from this time along with the tree Inuyasha was attached too. The well was sealed and now it is open and Mistress Centipede was in it because she dragged me in. Maybe it has been open too long and is allowing the era to merge."
