So this chapter revealed many, many things. Indra indeed lost against Ashura, we finally know that for certain since some Uchiha fans still had hopes. Naruto referred to Sasuke's technique as Shunshin so it's indeed S/T technique. We see how Hamura looks like. Not much surprising there, it was predicted that he'd have Byakugan. Essentially, Kaguya's will is the thing that started all this cycle of hatred, bribed and tempted the Uchiha clan to revolt throughout the generations. Also, we see that Kaguya, at the end of the day, is one ugly psychotic *****.
