The irony about Walter having already warned Ben about the packages does not escape him - rather, it haunts him.

What he can actually do relating to that emotion, however, is to minimize his away time by as much as possible - and evade any attention from moving abnormally quickly, as well.

Once he is certain the water is undisturbed, he opens and offers the bottle (not a glass, something that Ben would have to think about handling gently) to Benjiro.

"I picked up some wet wipes on my way back," he says. "Though those may not be the best option."

At least in terms of getting it all.
