Emerald asks why he shouldn't be worried about it. Emerald also mentions Joyride's apprehension when she examined the amulet. She said it might be influencing his actions and thoughts.
Sepulcher chuckles.
"Yes. I imagine Joyride probably doesn't know this symbol, but she likely knows the demons by it's name."
Emerald asks who the demon is.
"I doubt you would know who it is yourself, child."
Emerald says that all this is just making him worry more. He's been through a lot. He can handle whatever this bad news is. He just wants the truth.
"I am not your master. I will have a chat with Joyride about this when she shows up and I'll leave it to her to tell you about it or not. Now, like I said, don't worry too much about it. Run and play like most children your age do."
