Squall got less stances then Rinoa does, since he is rather steady then Rinoa's playfull atitude, but they were very easy to understand.

Movements

Squall's walk ritme is not much different then the moves from the other characters. His moves are very fast and straith, that's because he is very long, therefore his steps are also very far from each other. I think this is a very normal walk movement.

His run movement is rather weird looking, since when he is running he kind of bows to the front. His legs also are very wide from each other when running. Some statement can be because of the outfit he is wearing, but again this is not official.

When Squall stops walking or running, in other words when he is standing still, he seems to lean on his right leg, which I do to, and he left leg is relaxed to the side. Most people find this a great way to stand stil and to balance their wait on one leg, while the other relaxes. 

Lying on the ground

Squall got many different poses how to lay in his bed, wether it is on his back or on his left or right side, you can view them all, but I did not conclude them all at once, since right and left are equal. When he does, one of his arms are held under his head, the other close, while his legs are held up high.

When he lies on his back, both his arms are held under his head to lean. The rest of his body is very relaxated. At one moment Squall lies on his front to watch some soldiers interacting with each other. Both his arms are crossed over each other and his legs are wide open.

Sitting and kneeling

I really like the way Squall sits on a chair or sofa, suprisingly I sometimes do to. When he is sitting, Squall bows to the front and crosses his arms to his chest, while letting them lean on his knees. It's some sort of his habit, but it might also give away a rejection or not caring/not listening look. I also think that Squall, when he looks down, is infact listening and thinking inside his mind.

Another sitting habit, is the original, but yet rare one. This mostly seen at the end of the first disc. Squall here sits on the edge of the structure and leans on his two hands, whom are aside from his body. His right leg and left leg are not on the same lenght either.

Squall is mostly known for his special kneeling action, like Rinoa. When kneeling, Squall leans for this time on his left leg, while his right legs stands up. His right arm also lies on his right leg, while his other arm hangs across his side. This kneeling is used on many occassions, but also when the other are sitting down, Squall has the habit to kneel then to sit.

At one occassion, Squall drops down, but this is because the cell is moving and he is still weak to hold his balance. This is not a special move, but I thought it would have been nice to conclude here. When he drops down, he falls on both his knees and leans on his two hands. (His hair would probably fall down aswell *wink*)

Habits or annoyance?

Squall pity enough does not have any happy action throughout the game, unless it's in the videos, which are not concluded in here. Since then, Squall has been given other actions, which Rinoa does not or rarely shows. Therefore, Squall has a lot of habits, but they are also mere rejection or dissappointment habits.

When Squall is talking, and someone is giggling or making him/herself emberassed, Squall occassionly puts his left hand in his wheist, by means of what's happening? This is a mere personal habit, then anything else.

Something similar is the when he is annoyed, either because it annoy's him or he wants complete silence. This rejection also comes with putting his hand on his weist, but this time with the right arm. It is not sure if the difference in the left and right is right, or his arm always points to the left of the screen. I don't know, but I'll find out soon. Well, also different then the other stance, Squall here completely looks out the other way from the person as a means of annoyance.

Another example of being annoyed is pretty much similar to the other one, only here Squall crosses his arms together inclose to his chest and looks to the other way. Also different is that he talks during this sequence, mostly about what he does not care or does care, but also how he thinks.

When someone is asking something to Squall, meaning that he needs to decide for the group, he occassionally puts his right hand on top of his head, meaning as he would say "why are they asking this to me?" or "give me a break". This is also a more common stance for Squall.

Other habits do not have a big role throughouth the game and sometimes means the same. Squall sometimes moves his left arm as a means of saying something, like if they understand what he is trying to say or just a mere habit with no means whatsoever. When he is wants to point, he points with is right arm, very quickly.

One moment in the game, Squall does not know more about a certain fact, he actually will wave to the camera. Well, he does wave with his right arm as a means of "not knowing".

Emotions

There are some sequences where Squall shows of more emotions then anywhere else in the game. Like if Squall get's embarassed because someone gives good feedback he tends to blush? (I guess...) Well, whatever the case, Squall, at one time, bows to the front and holds his hand in front of his face. I do not know what he actually is doing or what the meaning behind it all is, but I guess it might be something emotional to himself.

Also since he has been lonely for ages, Squall does not like to be touched on which form that is. At one point Rinoa clinched herself onto Squall, because she wanted to be comforted. You could easily see that Squall did not like that sort of feeling. While sighting he reassured to her that she would be save close to him, but everyone does know that is was to get her of from him. Another situation is at the point Irvine tries pushing Squall to rescue Rinoa, but as Irvine touches Squall, he moves away fast.

When Squall get's really emotional or even afraid, unsure about the situation he is in (mostly when it has to do with his unknown past), Squall tends to loose control over himself. You can easily see it through him touching his heart with his right hand. Squall becomes intertwined with many thoughts and mainly asks to stop. This has a big input regarding Ellone.

At one point he also freaks out, by doing this, he swiftly moves his left hand accross himself to the back. This kinda happens fast, so it is hard to explain. One situation this happens is when Squall wants to rescue his home, his Garden.

Rules and speculations

Being a member of SeeD or even a SeeD cadet requires to follow many rules. Squall is of course a perfect student, so he does follow the rules or be polite when needed to his superiors.

To be a respected student, wether you are a Cadet or Member of SeeD, it is alway's used to salute to teachers in missions or even to the headmaster. When saluting, Squall points his right arm up just in front of him, with the back palm of his hand pointed outwards. I think the salute is really weird, but alteast much better then if he would act as a soldier in our world.

when something is asked to Squall, for either a mission guide or if he understands or is ready, Squall often nods with his head to say "yes". He does not use any words for his expressions, but his stances are always clear.

Opposite of spirited

Squall is easily irritated and soon get's angry about certain things. As for know let's view the stance when he doesn't know what is happening, a kind of shocking movement. When it happens (Balamb Garden moves), Squall moves looking from right to left and holding his balance with his left leg, while his right one is otherwise balanced at the front side.

At one point Squall got really tired of having to listen to people with complains, this is a matter with Irvine, whom tells how awesome he is, but eventually backs down at the last moment. Squall's get's frustrated by such people and puts his hand on his head, while moving it down to both sides.

On most occassions Squall get's really angry, this by showing it emotionally. He moves his left arm to quickly that it is difficult to completely view or capture a screenshot from it. He then moves both his arms to his face and moves it upwards (then downwards) as a means of "why me!?"
