Shino: Encouraging Hinata
Hinata's main conflict throughout the series is internal. She wants to improve. She wants to change. She wants to become strong and earn the respect of her comrades, family, and her hero, Naruto. Does Hinata have any external allies in this internal struggle to improve? Yes, she does -- we know him as Shino Aburame, the stoic bug-using ninja of Team Kurenai.
Listen to this private exchange between Hinata and Shino:
"Wow, it must be so nice to have something that you're good at and that you enjoy, like the three of you have."
In the original clip, Shino replies: "You'll find your strength too, Hinata"
In the flashback, Shino replies: "You should find something like that."
During the Bikochu arc, it begins raining, which is an indication that their time is up. Hinata begins crying, feeling like she wasn't any help. Shino appears and gives her hope, telling her that the conditions created by rain will make it easier for her Byakugan to detect the heat signatures of living creatures.
"Hinata.. The rain.. it might actually be to your advantage.."
"What do you mean, Shino?"
"Think about it. When the surrounding temperature cools, it's easier to see the heat signatures of living creatures."
Notice -- Shino appears near Hinata and gives her this information immediately after the tears stopped rolling from her eyes. Did he see her crying?
After this, Hinata is given a new wave of confidence, and she uses her Byakugan to locate the Bikochu. Naruto then catches it. From this timeline of events, it would appear that Naruto, who is usually her inspiration, was not the one who gave her the confidence to locate the Bikochu -- it was Shino
. Shino really seems to care about boosting Hinata's confidence.
While Shino explains to Naruto how hard Hinata trained, several flashbacks occur. This is one of them. In it, Hinata is thrown to the ground by the attacks of Shino and Kiba. Kiba runs to her and yells:
"Hey! Maybe we should slow dow..!"
Hinata disputes this, telling Kiba that if he wants her to improve, then he has to come at her full force. Notice that Shino runs over to make sure that she's okay, but makes no indication that he wants to begin going easy on her.
He does not second Kiba's comment. Kiba frequently makes remarks that make Hinata feel less confident about herself. Kiba doesn't mean to make her feel this way, and is just looking out for her, but Shino never seconds these comments. He believes in Hinata's potential and is tactful enough to know how remarks like this affect her self-confidence.
When Kiba tells Hinata "not to go soft" (English dub: "Be strong for this, Hinata") she looks down, as the remark highlights her reputation for going soft. Shino stays silent. After Kiba is defeated by Naruto, he tells Hinata to forfeit if she is matched up against Gaara or Neji. This is, of course, something that would lower her confidence. Shino does the opposite during the exams, as the next picture will show.
When Shino finishes with Zaku, he walks back to his team. Kurenai is creeped out. Kiba and Hinata compliment him. Hinata stutters out a congratulations, and Shino says:
"See that you two do the same."
Based on his tone of voice and the demanding way he words it, one might conclude that Shino is being arrogant. This is what Kiba thinks -- however, based on other events in the series, I don't believe that.
While I can only theorize, I don't think Shino would have said this if Hinata was kicked out and only he and Kiba remained. Shino has known Kiba long enough to know that he's got plenty of confidence. I believe that his apparently arrogant words were a subtle cheer for Hinata, disguised as a message for both she and Kiba.
Also, notice -- While Kiba is advising her to forfeit and telling her 'not to go soft', Shino is telling her that he expects her to shine as bright as him.
Shino: Encouraging Others To Believe In Hinata
Generally, others look down on Hinata as "weak", "hesitant", "weird", etc. -- even Naruto considers her a "dark weirdo" when they first meet. There is another voice, though, telling these 'others' how strong she really is. That voice belongs to Shino Aburame.
During the Bikochu arc, Hinata is kidnapped and the rest of the squad is trapped in a wax created by Suzumebachi Kamizuru's Queen Bee. Shino looks over to Naruto and asks him if he's worried about her. He says that he is, and Shino replies in a very serious voice:
"She's strong you know.. Hinata.. Much stronger than you think."
Just before Naruto is about to be attacked by Jibachi Kamizuru, Hinata throws an explosive-wrapped kunai in between them, and appears after the smoke from the explosion clears. While Naruto believed that she was dead, Shino's lack of concern (and even apparent submission to the Kamizuru siblings' goals -- "Okay, you win..") after hearing about her 'death', despite the fact that he was seriously concerned when she went into cardiac arrest during the Chuunin exams, shows that he believed in her the whole time and knew that she was alive.
The picture depicts Shino beginning to explain Hinata's training to Naruto. He begins this after Hinata performs "Protective Eight-Trigrams, Sixty-Four Palms" and Naruto expresses disbelief that Hinata could be capable of performing such an amazing technique.
"The Hinata you know is from long ago.."
"What are you talking about?"
"It's been awhile since the Chuunin exam and you've learned many new Jutsu since then, while in that time, Hinata has been developing as well."
"She's been training especially hard."
(Flashback of Hinata asking Shino to help her train)
"Hinata was so concerned about her purpose as a ninja. She wanted to be able to offer something.. unique."
(Flashback of Hinata getting thrown around by the attacks of Shino and Kiba during training, then telling Kiba not to go easy on her)
(Flashback of Hinata training in the water)
"After months of harsh training, Hinata discovered her own style, and her own special jutsu. What you're seeing is the result of that training."
"Because of her hard training, her Chakra control has improved dramatically.. and you just saw the jutsu she's perfected.. Protective Eight-Trigrams Sixty-Four Palms. Hinata took her superior flexibility, and combined it with fine-tuned Chakra control, defend off attacks from all directions at once. It's the ultimate defense jutsu. But it's different from Neji's technique. It's Hinata's own jutsu. She pushed herself hard, and it finally paid off for her."
That's quite a mouthful for the normally quiet Shino Aburame. In my opinion, simply by breaking his normally quiet nature and giving Naruto a detailed explanation of how Hinata became stronger, he is showing how much he cares about her, and how much of his heart he put into training her to this point.
His speech isn't finished, though. The final part of it is so interesting, in relation to ShinoHina and Shino's influence on NaruHina, that it deserves it's own little segment.
Shino concludes his "Hinata Is Awesome. Believe it!" speech with:
"Through it all, she wanted to win the respect of her father, the respect of her fellow shinobi, and especially, the respect of you, Naruto."
Tell me I'm grasping at straws, but his voice changes and becomes more solemn when he says "the respect of you, Naruto" -- Is Shino jealous? Is he trying to clue Naruto in for Hinata, and that's why there are signs of sadness in his "Get a clue, Naruto! She likes you!" statement.
