I'm looking at the basis of this settup. The Jailer would function as a type of doctor/protection role in that settup, with the benefit of protecting his target but preventing them from using their ability. It would also function potetntially stop a goon from attacking. However, if that was case, then based on the flavor, with Blade escaping the zoo, it would imply that Blade would have been jailed, as the zoo serves as a type of jail, which Zambi claims not to have done. Blade's name being mentioned in the flavor is likely due to a role modifier, that he or someone else may have. If it was a ploy to jail blade, reveal his name, and play as if he was attacked, then that would make sense of some things, though I do not think that is the case. I'm looking for utility in Zambi's role, as it stands now, it doesn't appear to be so.
