Nova was moving, as soon as it fired, getting out of the blast radius of it. It was well placed, though, and he almost immediately starts coughing, as his goons open up with weapons fire. Star charges, aiming for one furthest from the cloud, pinning the goons between her and tear gas; an effective combination. Ghost is already invisible, so it's hard to see what she's doing, but the fact that all the bullets seem to be missing him means she's probably doing a good job of it.
