I don't own anything or make any money off of anything Naruto.

The mid-afternoon training wrecked Team 7's subordinates down to the nerves, reaching the point where even Sasuke graduated from 'passive aggressive scowl' to 'growling through gritted teeth'. His agitation grew with the understanding of his limitations and whether he knew it or not, it was the first step to learning composure while failing. If Sasuke let his anger control him then there was no getting past revenge, even if it was fulfilled. He hoped the sullen boy would learn this before going down the wrong path.
The pink-haired female's behavior had altered over the hours as well. As their sensei continually attacked, capturing them in one of his varied jutsu after another, her focus was changing. Before she would yell after the Uchihia, running in a dainty manner and harboring foolish dreams of saving him. Now they were transforming into grunts and cries of battle. With each passing attack her voice lowered as he subconsciously instilled in her that they best way to protect those you care for is to not forget about yourself. When they first formed the team her devotion to the boy was displayed in high octaves and useless gestures. If she truly cared Sakura would need to protect them with her strength, not cry after them.
Naruto, however, never altered his method of head-on attacks. His voice never diminished and attacks never varied, even when he went crashing through the practice field. Watching the boy stand back up yet again, Kakashi sighed, but did not feel the training useless for him either. Jutsu could come later, as well as learning to keep one's mouth shut. The blond boy will change in his style eventually, but that was not important now.
He knew this boy would be hunted, if not for the seal on his body then for the identity almost no one knew about, even though the hair should give it away. For Naruto to become strong he needed to do exactly what he was doing now; falling down and getting back up countless times. In time, his stamina will prove to be more beneficial than his chakra.
However, after each attack the kyuubi boy made sure that his team was alright and ensured them that victory was easily theirs. Kakashi smiled, keeping it hidden under his mask, as he regarded Naruto's never-ending loyalty to his friends.
Hopefully, some things will never change.
