He knows where Geonmu is... Used Crystal to even reach out to Teo and I bet he knows the relationship of Geonmu/Gunmu and Teo.
So, this is Teo vs Jin in the end, like who will possess Geonmu in the end... wait! just how did Jin got a high position after him being shot at the flashback? who is his boss or did he kill the boss??
