Juugo might be rushing to Konoha while in Karin's body because Nagato was switched with Ami.

I'm thinking he might get a mission to Konoha sooner or later, if only as a pre-emptive measure to hopefully forestall terrible panics in the future? IDK it kind of depends on how terribly, or well, the bodyswitch goes.

or! if people from Konoha respond to his panicked (and viewable to everyone) missive, he might feel inclined to go and say thank you in person. (writing is hard okay)
