In the scene where Tsunade is looking down to the crowd during the inaguration, the camera shifts behind her where you can see Jiraiya standing next to the council. Look closely at Jiraiya's face, you can see the red lines on his face. In the next scene, the camera shifts to his left side and the red line is gone.
At the end of the second round of the Chuunin exams when all the Jounins are gathered, Tenten says, "So that's Gai-sensei's rival." about Kakashi. But, we see in flashback here that she has seen Kakashi already.
Tsunade: From this day on, I shall protect the Hidden Leaf Village as the Fifth Hokage.
Gai: You and I are too alike. We cannot survive without our ninja way to guide us.
Gai: If I lose, I'll take five hundred laps around the Leaf Village, on my hands too.
Kakashi: There you go again.
Gai: That's a promise.
Kakashi: (Thinking) Great... Another one of his oddball self-imposed rules.
Young Lee: I want to show that I can be a splendid ninja as well, even if I do not have ninjutsu or genjutsu. I want to prove it to the whole world.
Gai: (Thinking) There's that look.
Young Neji: Hmph.
Young Lee: What? What is so funny?! You think I am joking? I mean it! I will become a splendid ninja just by using Taijutsu and nothing else.
Young Neji: You nitwit. Without Ninjutsu or Genjutsu you can hardly call yourself a ninja now can you. Do you remember when they told you that you were the first person to graduate who could only use Taijutsu. They weren't saying that because it was impressive, they only meant that it was unusual.
Young Lee: Gah! (Gets angry)
Gai: Listen up. If you've got the passion, that isn't necessarily the case. With the right amount of passion, and some healthy competition to spur each other on, you'll all be great ninja. You'll all still have to work your butts off though.
Guy: Lee, there's absolutely no doubt in my mind that the operation will be a success! And in the 1/1000th, no, 1/1000000th chance something goes wrong, I will die with you.
Lee: (To Gai) When I complained that effort alone couldn't beat a genius, you said to me that I'm a genius of hard work. That's when you taught me the importance of believing in myself. But... this time, even if I put forth effort, or even if I believe in myself, it doesn't look like it's going to help. Gai-sensei, please tell me... Why am I the only one that's turned out like this?!
Gai: (To Lee) You, who put in so much effort...The operation will definately succeed. For sure, the way to success will open. Just in case...No, suppose the worst happens. We will die together. Since I met you, my purpose has been to make sure you become a great ninja. That's a promise.
Kakashi: It's my turn to decide the event this time, right?
Gai: What would you like to do? A taijutsu battle? A 100-meter race? Snorkeling? I don't mind if it's an eating contest.
Kakashi: Hey now... Well then...
Gai: What is it?!
Kakashi: Rock, Paper, Scissors.
Gai: Rock, paper, scissors? Are you trying to settle it with something like that?
Kakashi: Like they say, luck is also part of one's strength. Plus it requires insight and reflexes. It's a great match.
Gai: I-I see...
