Nice! I love how you balance character development with action in this fic, it seems like its hard to have both in most fanfic now days. Your characterization is perfect. I just re read the whole teamwork series, and I gotta say, the pacing of the storyline is wonderful.

... by the way, this "Their future children." purrrrr

Heres a random thought too, how is Nekobaa going to react to Sasuke having the Cat summon contract? Or are her nincats different?
