Perhaps not a wind, but a distracting thump against the doors in the room next door, giving them a little shake. There's also a low rumbling noise, some kind of strange animal noise, a bellow, not very low pitched, and given the thing making the noises, young as he is, no surprise that his roar squeaks a bit.
See, he's taking his stress out on a punching bag, and giving that bag quite a beating, so much so that he's thrown it into the doors.
A moment later, the doors fly open as Shad pounces onto the bag with enough force to throw the doors open and slide forward several yards.
If the 300 pound punching bag were a person, well... It wasn't getting up.
