Carmilla and Lillith were chatting about girls as they took a stroll before dress rehearsals when a water balloon suddenly crashed into the younger twin. 

"MY DRESS!" Carmilla shrieked. "Do you have any idea how long it's going take to clean this?!" She was about to continue when she noticed the fog spreading from the still-dripping stain. It quickly enveloped her, leaving neither route nor time for escape.

Lillith, being less concerned with the stain, reflexively shot away from her sister the moment the fog started to form. When the fog dissipated enough to see Carmilla through the haze, she was looking around and blinking slowly, as if she had been unexpectedly awakened before sundown.  It seemed she was too confused to even think to hide her confusion, something her pride would normally never allow her to forgo.

Her sister dodged a second ballon, then whipped her head around to find the source. Lock was small, but not enough to completely hide himself in the shadows when someone was actively looking for him. She used her vampiric speed to launch herself at him before he could loose another balloon, knocked the slingshot out of his hand, and loomed over him menacingly.

"Just [i]what[/i] do you think you're doing?" she demanded.
