Ok. I should be sleeping by now, but I just had an epiphany of sorts. Aether, I need you to make sure I have your characters correct.

You have Suzume Uchiha and Nuno Hyūga on a team. Their other teammate, Seidō Sarutobi and their sensei, Inoran Yamanaka, were both killed on a mission before this training arc started (so before they are introduced). Correct?

I have Satori Aburame, who will be on a team with the newly added Akari Kazeshima, and a sensei that will soon be made. They will have a third teammate that is not thought of yet.

But. If this third member also died before their team gets introduced, they would need a replacement. Now we have two teams, both with three members and a sensei, getting beat on a mission. Compared to the four member and sensei, Team Cho Li. This would make the Leaf Village want to keep the four student teams during the war, so they combine the two. Nuno and Suzume will join Satori and Akari with their sensei.

... just had to get all that out before I forgot it during sleep.
