How did Derek know about Erica, Isaac, and Boyd? How did he even know about their suffering and problems in School (and in Isaac's case, at home)? Also, remember that scene at the hospital with Erica. She asked him "Who are you?" and his response was "Lets just say we have a mutual friend?". Who was that mutual friend? Was it Scott? That scene always confused me. I just assumed it was Scott that he was talking about but I'm still iffy about it. Does anyone know?
