Like a novel-verse equivalent to the lollipop wrapper - imagine ZYL throwing something like that out! /o\

OMG!!! /o\ /o\ /o\

(Though I feel like mementos with that much significance are things SW would keep on his person, and novel!SW has the soulfire, so maybe he hasn't been compelled to save ZYL's discarded rubbish for thousands of years? :D)

(And yeah, SW doesn't really live in that flat, but he does keep his Kunlun shrine there, so ...)

Yes, and once ZYL discovers that, he backs off his plan...
