Dinah barely had time to return the wink and smile when Dean was tossed across the room. She looked for some sign of the ghost as she felt pressure driving her back as well. She hit the wall with a loud thud and couldn't quite get her limbs to move.
She could still scream though. There was a chance that it wouldn't help, but maybe? It was worth a shot. She looked at the spectral form of a dead woman and let out a scream loud enough and strong enough to interrupt the frequency of anything nearby.
It worked and the ghost blinked out of sight. Dinah dropped to her feet, already anticipating that the impact with the wall might cause some soreness tomorrow.
