After a few knee-jerking motions to the gut, the third vampire fell to the ground, doubling over in pain. Doing a flip over his shoulders so that she was behind him, Buffy didn't waste a moment. She plunged the stake into his back and right through his heart, sending him floating about in a puff of dust.
It was then that she caught onto the presence of someone else nearby, now that she only had one vampire to contend with. She glanced towards Supergirl, who she knew to be Kara, and gave a small nod of acknowledgment. The vampire tried to take advantage of this moment of distraction and rush the Slayer, and he succeeded. Not for long, though. She stumbled back a little and took a cracking punch to the jaw, but she was back in action almost right away.
"Like to watch, do you?" she asked with a smirk, knocking the vampire back with a return punch to the nose. She wanted to string this one along a bit. He looked the most ridiculous with his ripped sleeves and mismatched boots.
