Wasn't obito the one who taught nagato to control the rinnegan? Also I think Obito was attached to his original mangeykyou which was why I think he didn't take the second rinnegan. Also I do want to point out that obito Has both components required for rinnegan. The uchiha heritage(his birth right) And Hashirama's cells the Senju heritage.
