A few seconds after Buffy's confirmation, the green-skinned alien settled any doubts by shifting into game face itself, growling and leaping up as if nothing that had happened so far had fazed it at all. If anything, pottery to the head had focused it, made it angry. It shouted something in a language Wanda didn't know, but she could read the anger in its mind. And in its actions, as it took a swing at her, moving much faster than Wanda expected.
Wanda pelted it with red energy, forcing it back, then back again with another flurry. She just needed a second, a stake, how was that supposed to work again? The idea of a stake to the heart had seemed much simpler when not confronted by a fast-moving vampire. Never mind alien anatomy.
If it got close enough to grab her, she ... The thought was messy. Unpleasant. She would not let it get close. Her energy bolts were having an effect, but the concussive damage only slowed it down. Wanda was afraid she would have to batter it into literal pulp before she could stop it. A quick glance to the side showed Buffy wrestling with her vampire; busy, then.
Stake it was then...
The first attempt hit a rib, the second some fleshy part that wasn't the heart, and the third it was back to rib again. Humanoids had a lot of ribs, apparently. Wanda made a twisting motion that pulled the stake back to her with her powers, and generated a wave of red to protect her, but now it was the vampire forcing her back, and she tripped over the outflung arm of the first victim.
One unguarded instant, one vampire diving at her with wide smiling fangs that looked about ten inches long to Wanda. One stake raised in defense, one vampire twisting away, ducking to roll out of its dive, and Wanda realized that she'd actually almost hit the heart that time.
So that's where the heart was...
Wanda blasted the vampire back and sent her stake whirling after it, a pulse of red energy forcing it home.
Dust.
And all of that from beginning to end in the time it would take to brush her teeth, Wanda thought with an internal giggle. It seemed unreal, somehow, but battles were like that, she remembered. So quick.
"I'm okay," she said, her voice a little unsteady. She was breathing hard. "It's... gone."
