Why didn't obito get kabuto to reanimate rin or if possible nagato to revive her?

[EliteKage]

You see Kabuto and Obito weren't really friends Obito was being forced to let Kabuto work with him and Kabuto had plans for his own rather than helping Obito

Either way if he edo tensied her what would be the use when she would be 13-15 years old ...

The age is not important tobi wants her for his fantasies.
