That stream of water looks refreshing, but do we have any idea how deep it runs? Better to avoid it while we still lack mobility.

Maybe we should try inchworming up the tube, further away from the lamp? Hopefully we'll get a chance to see further up.

Sorry, sorry! Didn't know all comments counted in the story :p Gave me a good laugh though.

Depending on how good your night vision is, killing the lamp might be a good idea. Before you do, though, see if you can use it to burn through your bindings.

Even though the gag might be gone, would probably be best to refrain from making any kind of noise. If a smell is fresh, they could return soon.

Is there any other light visible from where you are? Or is the lava tube the only thing seen?

See if you can rinse that nasty taste out of your mouth and get a quick drink.

Can you see what is in the box ?
