[Sounds like a plan... Except, you know, stores carrying food are shut down and impossible to get into. Other odd ones are open, many not the type to be useful at times like this - one carrying art supplies, a sports shop (maybe someone wants to play basketball inside the castle??) a weird little shop selling old fashioned tea-sets, and others.]
[But at least their trip won't be entirely unsuccessful. It's clear there're animals lurking around that weren't there before, for example.]
