[Hanzo follows the scent of his brother through all the chaos, just wanting to check up on him. Due to his lack of bracelet and stubbornness about wearing it he's literally become a large wolf. There are only bits of his humanity left in his brain, but it's not enough to allow him the ability to communicate with speech. So instead when he does locate Genji he circles around him excitedly.
His tail wags and he jumps up on him to lick his face like it might heal his scars and when that doesn't work he just sits down in front of him. There's a whole lot going on around him. People struggling with their transformations and acting impulsively or deliberately aggressive. Hanzo just sits there, glancing around to make sure there's nothing threatening himself of Genji. Other than that he's fairly calm for some reason. Well, that and being a giant wolf.]
