Stowaway revealed

<Away team 1 campsite>
Zack sat with his back to a tree, watching as the sky darkened.
He clutched his rifle with a white-knuckled grip, spotting movement
at the edge of his vision only to turn and see a tumbling leaf or one
of the other members of the team adjusting in their sleeping bags.
Like he was going to get any sleep.
He blinked. It was morning.
Well, maybe he'd get a little sleep after all. As he stood, he
felt his back crack as several vertebrae suddenly remembered that his
spine was actually a fairly straight affair.
The rest of the team was breaking down camp when the security
officers started to get agitated over something on the ground. Zack
moseyed over to see what all the fuss was about.
There were several footprints in the soil. Large, non-human
footprints.
They were talking with White Wolf about some sort of attack that
team 2 had weathered last night. Apparently there were nasty
beasties afoot.
All right. He'd had enough. Pulling out Cubie's control panel,
he activated her. She appeared, decked out in camoflage utilities.
Zack smiled. "Hey, sweetie. I-"
Cubie whipped around, catching him in the forehead with a combat
boot, then drew a combat knife and dove for him. Just before her
blade thumped into his chest, she disappeared.
Zack staggered dizzily, stars filling his line of sight. He'd
tapped Cubie's deactivate button reflexively when she'd kicked him,
but his brains were still scrambled from the blow.
Finally his vision cleared and he looked around. The rest of
the away team was staring at him.
He smiled weakly, hoping that there wasn't an imprint of Cubie's
boot on his forehead. "What?"
