User blog:NixtonV/Is Noel Karl's Brother?

Basically what the title asks. In the Summoner's Research Lab, the scientist Noel looks a lot like Karl. They have the same color eyes and hair, the only difference being that Noel is significantly younger. Noel's first trial, as well as his first clone of a living being, is of Karl. So what do you guys think? Is Karl Noel's older brother?
