If there was something wrong with Stacy, they probably weren't equipped to handle it. And this time there wasn't a Pilot to walk them through anything either. John followed Ian deeper into the tunnel, waiting for Ian to get his science geek on (hell yeah, he even brought a sample tube - good man) and trying to listen above the sound of his breathing echoing in the helmet. It sounded like...something. He couldn't place his finger on it, John tilting his head even though that wasn't gonna make a difference.

He turned and - okay, that was weird. The way back was blocked with what looked like a membrane, slick and slimy.

"Uh, hey Ian. Take a look at this." John didn't trust trying to shoot their way out. Something told him Stacy wouldn't take too kindly to getting shot in her guts.
