About Tsunade .. i believe her first priority was to get all wounded personnel out offthe woods {heal them asap for round 2}
and she can't fight while in healing mode... but probably if a pain drops by o say hello :hello: she'll kick his has :futon:
secondly i think mama toad [who went to look for food] will come to konaha o check on things and so find out bout pain
well kakashi has depleted all his chakra so he actually might be having an out of body experience {Cloud in advent children}
and then again kishi could just go to Saskue in the next chapter and so make everyone want to ikill him XD ...... maybe he wants to experience what kakashi is going thru XD
