X-Men Team 2: Storm/Shadowcat/OT Shatterstar
Kitty indicated that whatever they were hearing was above them. It made sense, but it also made her wonder where exactly were the stairs or the elevator? In order to have multiple levels, there had to be a way to move between them.
"Stairs?" She mouthed since Kitty was looking at her. While there may have been no reason to whisper, Storm did so anyway out of habit. In the few times she'd been in an espionage situation working with others, she had found the less sound anyone made, the better. One could never be completely certain of who was listening.
Storm had not drawn her weapon, nor would she make any attempt to do so until she was actually presented with an enemy where it was necessary. The air was still pregnant with the possibility of lightning though, following her as she slipped forward again to come to the edge of the hallway Kitty was looking down.
The footsteps continued, but they were moving away from them. Storm let Kitty take point because her abilities made it easier for her to be in front.
