The men sound calm, which means they haven't been found out...yet. Either way, they sound like they're planning on getting in sometime, and that doesn't bode well for Kaylee and Jamie if they've got reinforcements waiting out.

She fully intended on following Jamie, if anyone asked later, but ideas were ideas, and if this one could help them get out it was worth a shot. The tank. Kaylee's mind is working a mile a minute, and she's got a plan that just might work, at least in distracting the men away from them. It'll just take a bit of rigging...

Quietly as possible, she creeps back toward the tank. The bottom panel is long gone, thankfully, and she can reach the wires without problem. A few switches (not without a few burned fingers, thanks to the rain and its sharing water), and Kaylee motions for Jamie to go ahead into the tunnel before she shoves the last of the wires together. The tank comes to life with a deafening rumble after such a long silence, and the shouts on the other side of the rubble are immediately. It only takes another fix or two on Kaylee's part to get the tank moving, and then its heading out of the shelter while the mechanic is darting back toward Jamie and the tunnel.
