Back with Flora, Dark would disappear.

Jason smiled back slight, but then Dark appeared in the room. She takes in the scene. "Well, I was coming for my brother, but you'll have to do Jason. The Demons broke through." Jason sighed, and nodded. He turns back to Nozomi.
"If you let him die, I'll kill you." Both Dark and Jason disappear.

Back with Flora again, the two would reappear.
