Charlotte let the body drop to the ground, pulling her spiked bat free. She heard creaking from up above, and held her bat at the ready as she crept to the stairs. She started up, taking them slowly, but knowing that her footsteps were creaking just as badly as whatever was approaching her. The sounds got louder, and closer, until she was at a turn in the stairwell, and she jumped around the corner with a battle cry, her bat over her shoulder. Her cry died in her throat as she saw, finally, Bow Guy. Crossbow Guy, actually, aforementioned weapon aimed handily at her as she stood on the stairs below him. 

"Uh," she said lamely, bat still held unconsciously over her shoulder in a swinging position, "Hi."
