Owen was the first there. He could feel the tremble of the anticipation coursing through his veins like a drug as they approached. Down and down they went, travelling through a series of complicated passages that most of the team had passed through few times before.

Owen, however was an expert. Navigating his way through the tunnels like a rat he was soon at his destination.

A small door lay, set into the concrete wall, simplistic in comparison to the mighty vault most would expect to lie hidden so secretly. It wasn't even locked.

"Why all this trouble Jack?" asked Gwen, bemused by the complicated system.

Jack looked thoughtful for a moment, for once not as quick to the draw as usually expected. Gwen, noticing the pacified look on Jack's faced presumed correctly that perhaps Jack, as well as Ianto, pleasured in the facial structure of the other.

"Well Gwen, if an alien got hold of our erm, excrement, then all hell could break loose."

Owen turned around amused.

"So even our shit is a security problem now?"

"Not to put it in those terms," Tosh replied, "but basically yes."

A sarcastic grin transformed Owen's face.

"So, what on earth could the aliens do with our "excrement"? Control us like puppets on strings? Construct a disgusting Eiffel Tower? Use it as compost to harbour new life for their planet?"

"Wow, who knew the kid was so bright?" Jack asked, utterly amused.

"You do realise," Ianto started, "that all of the things you just mentioned could happen..."

"What on Earth would aliens want with an excrement Eiffel tower?" Gwen interrupted, thinking aloud.

"... if you'd let me finish I was about to tell you."

"Nah, it's alright mate," Owen's grin heightened, tapping Ianto on the soldier, "we all know it's simply art."

"Who in their right minds..."

CLANG

"Alright gang, that's enough. I think we got a bit off track there... ready to kick some alien butt?"

"Hell yeah," Owen replied, attentions shifting as he grasped his weapon more tightly, jamming his finger onto the trigger, bypassing the safety switch.

"Don't be too hasty Owen," Jack cautioned, "on three."

The team fanned out, Gwen and Ianto's torches lighting the dim corridor inbetween the intricate tunnels and the oddly placed door.

"One...Two...Three!" Jack shouted, kicking the door swiftly open as the team burst into action, surveying the room.
