Yea you probably should reread everything. Soken taught Uryu and they considered themselves the last of the Quincy. Hence the introduction of the Vandenreich being a surprise to everyone, the Quincy are supposed to be extinct as a species. Being only Ryuken and Uryu left. Ryuken had never given any interest in being a Quincy. If Soken knew of other Quincy in his lifetime he apparently kept quite about it. As we as the readers were never aware of it. Kirge never even mentions Ryuken.
