"Well it wouldn't really be tempting the rules if she only died once here." XIII looked at Charles. "With all this talk about multiple worlds it wouldn't be impossible that this ritual happened hundreds of times. But what if unlike how every other world is slightly or largely different, the woman was exactly the same each time?"

As Twain made his way over, a memory came to XIII so forcefully that it made him stagger backwards. He waved off any forms of help as he shook his head to clear it. Immediately, he rushed towards the paper and flipped it over, writing what he had heard down before he could forget it. Once he was done, he looked to both Charles and Twain. "Sorry about that. It seems that I may have remembered something from that night. I needed to write down what I could remember." He flipped over the paper to show the picture of the altar and the three circles. 

"To answer your question, Twain. this is representing a third circle to the ritual. Something was nagging at me about the fact that there was another."
