the fact that even drifter acknowladged how bad it is when Salidin says that Slone went through her own personal Dark Age, and he didnt make a joke or comment...yeah, least it tells you that Drifter knows when to hold his tounge. and the after effect that Drifter and Saldin have known each other since the Dark Age to the point where they have a decent history that even Salidin will share a drink with Drifter....Subtle but effective character development.
