Forum:Could it be possible that Zekk is a Sith Lord?

Could it be possible that Zekk is a Sith Lord? Let me explain: His parents died.(fear) He was once the Darkest Knight.(anger) Jaina has emotionally hurt him so many times its not funny. (hate) And whats the best way for him to get back at her...? Turn her twin brother into a Sith Lord. (vengence) There was also a comment he made in a conversation with Leia about "knowing something about hiding in the shadows"
