Here is the summary of Naruto chapter 619: While Suigetsu marvels being in the presence of Hashirama, Tobirama is displeased with being reincarnated by Orochimaru once again. Hashirama voices confusion, and is explained to by Hiruzen that Orochimaru must have undone the Dead Demon Consuming Seal and reincarnated the four of them. Minato is impressed by Orochimaru's ability to undo the seal, and Orochimaru explains that after Hiruzen robbed his ability to use his arms, Orochimaru went great lengths to research it. Hashirama inquires who Minato is, and is elated to learn he's the Fourth Hokage, taking it as a sign of Konoha's continued stability. Minato elaborates that his death and sealing preceded the Third's, much to the First's confusion. Hashirama wonders who is the Fifth, and is sunken when told it was Tsunade, asking if the village still stands, which Minato comments upon. Hashirama explains that as his first granddaughter, he spoiled her, which lead to her picking up bad habits from him, including his gambling. Suigetsu is silently underwhelmed by Hashirama's demeanour. Tobirama comments on the use of his technique, Orochimaru telling him that's it was rather straightforward, and that he should have kept it to himself, adding that his policies created instabilities that last to that day.
Tobirama asks if he was going attack Konoha again, Hiruzen is dejected, and Hashirama is disappointed the world still is in turmoil, and begins to reprehend his sibling, but is promptly silenced by him. Orochimaru denies he summoned them to destroy Konoha, and presents them to Sasuke. Tobirama jabs at the Uchiha for being in Orochimaru's company, to Hashirama's protest. Sasuke asks the Third about Itachi's mission, telling him how he learned of it from Tobi and Danzō after killing Itachi. Hiruzen confirms it, explaining that Itachi was very attuned to the village's history, and as such, never had strong ties to his own clan. Tobirama isn't surprised by the demise of the Uchiha clan, declaring he expected them to rebel. Orochimaru counters that the Second's actions contributed to the Uchiha's planned coup. Hashirama admonishes his sibling for his persecuting of the Uchiha, while Tobirama maintains he gave them a duty they could excel and justifies it by Madara's actions, saying the Uchiha clan is possessed by evil. Sasuke asks Tobirama why he feels that way towards the Uchiha, and is told that the general perception of the Uchiha as valuing techniques over love is mistaken. He elaborates that once the Uchiha know love, they're so caught up in it that in losing it, they're consumed by hatred. The loss leads to the awakening of the Sharingan, and the further they're consumed by hatred, the stronger their eyes become, using Madara as an example. Hashirama figures Madara loved his brother more than Itachi loved Sasuke. Tobirama tried to channel that power to Konoha's benefit, saying in the end, they served the greater good. Hashirama is outraged at his tone in front of a pure Uchiha child, and Sasuke activates his Mangekyō Sharingan, which Tobirama notices, stating he does not care the tone used, and that he's neither pure nor a child. Sasuke then asks Hashirama what is the legacy of the village, and what purpose do shinobi fill.
