Can we get to actually acting things out, or did the character already shoot himself while we were waiting?
...You snap back to reality after being entranced by the gun. You can't help but feel in danger when holding it.
Throw away the pills because going all test subject-y is a terrible idea. Instead, use the empty pill bottle to store the gunpowder.
Toss the spent shells away because who needs those.
Afterwards, go over and check what's inside the backpack. If there's enough room for the thermos and gun to fit, store them in it.
Can't you just put the pills in the backpack?
After checking for any extra pockets in the backpack, you put the gun, snacks, and thermos back into the pack. You're not sure what to do with the meds or the gunpowder, but you settle on the decision of dropping the meds and using the bottle for the gunpowder. You also remember your suit has pockets, although you doubt anything is in them and you don't bother checking.
As you walk off, you hesitate... and decide to put the pills in one of your backpack's pockets. You never know what might happen, after all.
You find out that you're actually on a cliff.
Then you hear yelling, and look down.
You think you can see a person, and five animals chasing them. You're pretty sure they're wolves, and you can make up the rest of what's going to happen if you don't intervene.
