The third and pervy sage would be in a corner fapping to Kushina .
The 4th and Kushina would be trying to question Obito about how'd he survive(Not knowing he killed them, they wouldn't be hostile).
Obito would actually ignore them, and him and Itachi would have hostile eye contact as if having a stare off, while Nagato watches the two of them .
Nagato sooner or later plans to allow Obito to have a horrible death, begging help from Itachi .
Only for Itachi to say "You're being too hasty Nagato, we need to wait"
Asuma would just be a dumb duck not knowing what to start doing .
I don't know if that's Neji though, if it is, he's even more irrelevant than HakuLol
Zabuza is likely to run around attacking everyone due to confusion .
Haku is likely to be the one telling him to cool down, and try to start slowly by asking everyone questions .
