Tanner canonically has a younger brother that the Elgen had access to at some point. In book 1 or 2 (I think), Hatch mentions how he used Tanner’s younger brother to convince Tanner to bring down his first plane. Was he kept alive in case Tanner turned on the Elgen? Was he killed after Hatch got Tanner in his hold? What happened to Tanners brother?
