Gavin:
Jacob looks around warily, not replying for a moment...
"Let's keep moving."
The flashlight under Malcolm's gun is a more focused light, illuminating further and brighter but less area than the lamp. Just from a cursory glance at the walls with this aid, you can already tell that there's a good chance of fossils: there's good sedimentary rock formations, and judging by the erosion it should be a decent site. But you'll have to get a better look at the site to be sure.
Finally, after about 5 minutes travel all told, you stop. Malcolm's spotlight illumines a sortof rock bridge, where there's about a metre wide of good walking space before slope suddenly drops down... and down. Beyond it is nothingness, even further than Malcolm's flashlight.
Jacob nods. "It's just ahead here... I'll go first. Here, take this. You'll need it more than me."
He hands you the lamp and strolls across, obviously practiced in such things. You follow behind, and it doesn't seem that bad... but nearing the bridge, that one metre seems mighty small space, especially on such uneven footing. Malcolm bumps into you from behind as you stop, and almost pushes you off the ledge, but manages to catch you from behind.
"Here, this should hold ya." He takes a cord from his belt and hooks it to one of your belt loops, securing you to him on a leash. "Should give you better incentive not to slip- that way, if you fall, you'll not only be dead but also a killer."
He grins, slapping you on the back.
Jacob turns back towards you, already invisible in the darkness.
"Hey, egghead, there's a..."
There's a whoosh, and a grunt, and he's cut off.
"...Jacob?"
Malcolm shines his flashlight off towards the bridge. Jacob is nowhere to be seen.
"Oh, f*ck."

TJ:
The girl continues to snore, straw hair now blowing in the slight breeze. A slight bit of drool runs out of the side of her mouth. If this is a trick, it's obviously a very bad one.
...Or a very good one.

Adela:
You and Vichi both strike in a perfectly coordinate attack. You swat it out of the air as it's flying by, and Vichi slams it into the ground. It's still quite conscious, and likely able to do more... but seems well demoralized. No meal is worth all this. It flies up and back into the tree, staring down at you and chattering angrily.
