Your words paint such a beautiful mental painting. I was especially touched by this line:

but infatuation doesn't make you let someone back into your home and life after years of silence, or follow them to the bottom of the world, or sit in a warehouse with them for two weeks while their brain eats itself. Doesn't tend to survive the bloody business of seeing them at their very worst, either.

*sighs happily* ^^
I'll be wearing this stupid grin all day thinking about this XD
