Crawling through air vents wasn't his favorite pastime, but at least OZ did a pretty good job of keeping the things clear. It was almost as if they wanted someone to take advantage of their presence. That wouldn't surprise Duo, considering who was in charge of things, but that was probably reading a little too far into things.

Coming up to the vent Heero had left open, Duo carefully lowered himself down in much the same way, making sure to keep from landing on Heero, not that he thought Heero would let him do such a thing. He offered a grin, once he was suitably grounded, gun at the ready, and nodded to Heero.
