Hmm I thought Infinite Tsukuyomi would've been something like caging everyone and making a perfect world. But considering RTN and the fact that Obito cast Tsukuyomi on both Naruto and Sakura they did share that universe.
Not sure how it will work if everyone is getting what they wanted.
Let's say Person A killed Person B. Person C killed Person A as a revenge and Person D killed Person C also for Revenge. Now Person D is among the alliance so only Person B should show up because Person D loved Person B.
That's idiotic imo.
If it will be casted on the alliance then probably we will see come backs of Itachi and probably even Sasuke's family. Naruto will reunite with Kushina albeit an OOC one.
Infinite Tsukuyomi is sounding more and more like a nightmare to try and make some sense of it.
