it's quite simple he's half hexenbiest half royal blood as explained in season two, he's not nick's half brother because he's eric's half brother (Eric is a royal prince if you don't know) H tryed to kill aunt marie cause it's to late for her to understand his ways so instead he uses nick to fend off his family and of course for some strange reason captain renard has extreme self control so that proably why nick hasen't seen him. Captain also saved julliet cause he has to keep nick in portland under his control, and nick had to take the potion to and he's not a grimm. The captain over all is just a guy trying to keep his family from finding all the keys. and now that season two is done his entire story has been reviled.
