If There’s a Scapegoat, Blame Danzo

Uchiha Setsuna's two Three-Tomoe Sharingan were taken by Meikyō and Fugaku, one each. Izanagi combined with a Three-Tomoe Sharingan practically represented an opportunity for a full recovery, making it extremely valuable. Just as everyone had expected, Uchiha Setsuna's disappearance caused a tremendous uproar within the clan. Many suspected Uchiha Fugaku had done it, because everyone in the clan knew about the terrible relationship between him and Uchiha Setsuna.
