"Yeah. Probably should... or at least tell them there might be..." trailing off at the thud, followed several seconds later by a splash, Cloud frowns. Doesn't stop or slow down, but cocks his head and tries to listen while he keeps his breathing slow and even and try to filter out the other sounds around them.

But he's not a SOLDIER, his senses are perfectly normal, no matter what he might try or wish for. Frowning, it takes a brief moment of distraction before his gaze flickers back to Victor, pretty sure he is the one playing the escort here, but...

"Cloud Strife." Since they were apparently doing full names and all. "... If something catches up with us, you should put your back to the wall and keep moving. You could probably use the supply bag if something gets past me."

Because even if it'd be a nice thought that it was some person making noises behind them without calling out, Cloud would bet it wasn't. They'd been talking since they met, after all, and whatever it was hadn't seemingly reacted to that.
