Well, it's gonna come through these, what are essentially holes in the ceiling, these sort of diffuser spots that get put up in the ceiling, and so this return is just gonna pull right through from that office up into the ceiling space, and then from there it's gonna go right into that that return system so that effectively that ceiling space becomes part of our overall duct system and when we do that that's referred to as the plenum. So you'll see the word plenum a few times, we'll talk about it at various points along the way, that concept allows even fewer times, when you might have to have the return duct and the supply duct cross each other, because when I start thinking about, from a system where I have this kind of system I might have, say, offices over here, and then here's my return duct, here's my supply duct, very far away from each other. This one is letting off towards the perimeter, but it's also letting off into the other office spaces and then the return is just up above the ceiling, going straight into that plenum space, so as the air comes out into the office, it eventually finds a space up into the ceiling, and then it will eventually get all the way over to that return system, and the same thing would happen from here.
