Kakashi thinks Lee's recovery is due to opening the "heal gate." This isn't about hard work, that kid...he's a genius.

Eight Celestial Inner Body Gates:

1. initial gate (open)

2. heal gate (energy)

3. life gate

4. harm gate (wound)

5. limit gate (forest)

6. view gate

7. wonder gate (insanity)

8. death gate

Lotus forcibly releases restraints using chakra.

Gai: You release the brain's restraint with the initial gate, then with the heal gate, you forcibly raise your stamina, then from opening the third, the life gate, you enter into the extreme lotus.

Opening all the gates is called the state of eight celestial gates.

Ends with Lee opening the fifth gate.

Ch 86: A Great Ninja...!! (ep 50)

Extreme Lotus - continuous high speed taijutsu that can't even be touched.

Gaara's memory of his family is fractured.

Gai explains regarding saving Lee: He is my beloved comrade.

Ends with Gai hugging Lee and calling him a great ninja.

Ch 87: Prelims Conclude (ep 50-51)

Lee has shattered bones and torn muscles throughout his body.

Neji thinks "Lee, you never realized it even at the end, the heavens will not allow a pawn that can only see victory at the cost of himself to advance..."

Kakashi thinks (in anime he says it to Gai) "I said some really arrogant things to you earlier, but when I really think about it...if I were in your circumstances. I probably wouldn't have been able to stop my student either..."

When Choji is stuck in the wall Dosu thinks "...to get out of that you'll have to spin in the opposite direction, which means you'll have to stop spinning completely once...that's when I'll attack...70% of the human body consists of water which conducts sound. In other words it's easy to transmit my destructive sound waves through any wall of flesh. As long as I stop your spinning, which presented the bigget difficulty, then I could guess where your ear drums would be and attack..." In the anime he just says 70% of the human body is made of water and water transmits sound.

Ends with Dosu declared the winner.

Ch 88: Where's Sasuke...!? (ep 51)

Kabuto has a scalpel in his hand and looks like he's about to cut Sasuke when suddenly Kakashi catches the scalpel. Kabuto says "Just what I'd expect of you Kakashi-san. To stop my attack on you from your blind spot." It's clearer here that Kabuto threw the scalpel at Kakashi rather than Kabuto trying to kill Sasuke and Kakashi somehow getting the scalpel away.

Ends with Kakashi and Kabuto facing off.

Ch 89: Naruto's Request...!! (ep 51)

Kakashi says (not in anime) "Wasn't your name Kabuto, a botton feeding no good ninja."

Kabuto says (not in anime) "I won't talk no matter what sort of torture or illusions you try on me, and I don't really like to fight.'

The fake Kabuto was an Anbu member whose face was surgically altered. Stitching can be seen around the jaw area. Kakashi thinks even the body disposal squad would be impressed.

Shows Naruto asking Sakura where Kakashi is, she responds probably with Sasuke.

Ends with Ebusi to be Naruto's trainer.
