He's a "decendent of a powerful line of Grimm royalty" as stated in NBC's Sasha Roiz bio. http://www.nbc.com/grimm/about/bios/cast/sasha-roiz/ That being said we still don't know his motives, plans for Nick etc. and the mystery is still very interesting. Cpt Renard's brother is supposed to appear in season 2, so we should start to learn more then.
