Well I guess that explains why the fox spirits all treat him like their lord, he probably literally is. Time travel shenanigans are going to make him meet them in the past (first time for them, second time for him).

I'm computer science, when dealing with organizing data such as in databases or in system memory, there are cases where the computer spends more time moving data around than actively working on said data. It is called "thrashing." It really slows down the system, as nothing really gets done.
This chapter was like an embodiment of that concept.
