Convincing the last one
After entering the cave and performing those strange actions, Chris had simply walked to one side of the cave wall and sat there, while everyone else stared at him.
"Hey, what the heck did you do? Why did you give Quinn blood?" Peter was the first to speak up. "And why are you acting so... so... I don't know, freakier than usual?"
Chris didn't reply right away. He was staring at the ground as if deep in thought, but he eventually processed what Peter had asked. Before he could answer, Hikel wanted answers too.
"You're going to have to explain in a lot more detail than you just did," Hikel said. "I know you and Edvard are working together, but right now your actions affect us all, so we need to know what's going on."
