Pain Killing

Jacob heard the phrase "The Devil Deals the Cards", and became a Biological Weapons System known simply as "Painkiller" who takes orders from the Director. He claims to be different than someone from Kysenia's past, but what he does remembers appears to be highly untrustworthy and incorrect. 
After a request from a party member, a portal opened up, resulting in an attack on the Tempest.  "Painkiller" escaped after injuring Mordin. 
Regardless of your view of him as friend or foe, it's probably not wise to leave such a capable person in the hands of someone like the "Director".  ...Or is it? The director has been known to hold negative feelings for Illiard, who appears to be a credible threat. Maybe it's best to just leave Jacob with him, in case it tips their balance of power and pits them against each other?
