Christopher has a brother?

"Hmm, what's with the cat" 

"I am not a cat!" Daniel growled as he bared his barely noticeable fangs at Christopher. "Now that's something you don't see every day," Christopher mused, but his eyes sharpened in the next moment and he appeared before Derek grabbed Daniel and reappeared at his seat.

Both Derek and Jake couldn't even react, as Christopher was too fast. They saw him holding the cheetah at its neck as it tried to fight back, but its efforts were useless.

"Banned tech," Christopher snarled, his tone deep as he gazed into the bright eyes of the cheetah. He was right, this was a product of that organization… a product of his brother.

When the cheetah spoke, Christopher could hear indignation at being called a cat. Robots, androids, and many other techs could talk, but none could produce such human emotion.
