Cale's Room A Few Days Ago
"In the elixirs I send you, you need to put something personal to the identity you are going to assume," Fredrich said, speaking to Cale in the hologram.
He explained the nature of the elixirs he was sending him and explained what to do.
"Something personal?" Cale asked with a frown, and a smile flickered on Fredrich's lips. It was so fast that Cale made sure he was seeing it right.
"Yes, for example, if you want to look and sound like me, you need to put a part of my body into the elixirs. My hair, my nails, my saliva..."
"Okay, I see what you mean," Cale said with a face like he was about to throw up when he heard Perez's voice of disgust coming from behind Fredrich.
"That's disgusting!"
"There is no disgusting in science, stupid boy," Reyna mocked Perez.
"So do I need to add hair for three different elixirs?"
