Danzo notices young Shino when strolling along with Shino's father and demands that a member of the Aburame clan be donated to the foundation, and he also mentions that an Uchiha member has been confirmed to join the foundation.
Refer to Ep. 317 "Shino vs. Torune!", is he/she in any way be this one mentioned on Who is this other Uchiha member?? The reasoning is because when Shino is young, Naruto and Sasuke are young too... so I'm sure that Sasuke's the only Uchiha alive at that point and the foundation always wished to kill all the Uchiha.
Or is it simply that the timeline is just before Uchiha massacre? and the Uchiha member being mentioned is just an ordinary member not worth mentioning?
