One thing has made me think, because Obito is being forced to use the Rinne Tensei, if he tries to resist and use it on someone else, lets say Neji, sure Neji would be revived and his body rejuvinated, but would the sealing of the byakugan be overwritten or remain?
Its situations like this in animation series and even games people have dubbed this situation "The spell speed effect" based off the Yu-gi-oh card game, in the game there were different types of "item" cards you could say that had priority effects, some effect with a higher priority could overried or negate another. Some lower ones could remain in effect but nullified under a higher power. In the case of Naruto this has come up many times like when Orochimaru used the 5 pronged seal on Naruto, it did not disrupt the seal but prevented Kurama from leaking chakra to Naruto. The seal for Kurama was intact but the transmission for chakra disrupted. Again recently in the war, The gold and silver brothers were sealed in the jar and pot. Kabuto released the edo tensei under Itachi, but they were unreleased so the jar and pot blocked the gold and silver brothers from being released.
This happens with Neji being revived would he really be set free due to revival or would be come back but physically blind, unable to open his eyes?
At this point, anything with Sakura getting a speculated temporary death is looking less likely though, I mean if Obito did use it on her as giving Naruto the chance he lost or whatever, yeah that would have been his redemtion but that event is not going to come at this point. Sakura is needed to stay alive with the whole Sasuke ordeal. Not to mention she has a healing job to be ready for, I mean I think she will fight more maybe when Tsunade comes but for any purposes, I just don't see her getting harmed.
The whole Obito/Rin NaruSaku parallel, it still does exist I mean its there, the teams are paralleled for obvious reasons mainly due to team dynamic and Obito and kakashi represent the opposite of what Naruto and Sasuke took in life though team minato had a dark fate. Yeah rin died herself but she still has the direct dynamics that link to Sakura as the orginal team 7 did, its also again worth mentioning how both Naruto and Obito were guess you can say, burdened by a love (this is similar to how Sakura and Tsunade's love for another is paralleled, as Naruto and Jiraya loved them, they loved Sasuke and Dan respectively but both Sakura and Tsunade lost their loves, Sasuke merely ran away while Tsunades brother and dan died so they both figuritly lost their loves) for Naruto and Obito, both had pains for the girl they loved, for Naruto it was the promise and for Obito it was the world he viewed as corrupted which lead to Rins death. Naruto though has a chance for Sakura in part because he was able to impact her and for the fact that well, she is still alive.
