>Derrick: First off, it's important to establish what Garry would do without these items for the basis of a plan. Go through his basic plan first and then work together to figure out if there's anything that's reducing the options you can take or figure out what is likely to go wrong. Then determine what items, if any, would be helpful in mitigating that. If the answer is you don't need any items in particular then just grab some stuff that's generally useful: stuff like (but not limited to) a flashlight to see in the dark, duct tape and paracord for tying or making things, and a watch so you can make sure you know what time it is. There's two of you so you can spread things among yourselves as well.

Seconding this. This post basically sums everything we need to do before knowing more, I guess. What did Derrick buy the hourglass for, though? I have no idea.
