Selina was to preoccupied with the fact she'd just managed to floor Dinah, and put most of her weight and energy into to it to notice the legs sweeping out to catch her out. She tried to jump one but missed the other, falling backwards over feet and hitting mat - only a little less hard than Dinah.
Landing with a thud and an audible groan, Selina looking over at her quickly before rolling away, still on the floor but far enough away that she couldn't get a hold on her. Far enough away to try and figure out how this was going to go.
"You okay?" Selina asked matter of factly, expecting the answer to be a resounding yes.
