This is mostly for Snowysnowgirl123 or anyone that reads my book(s) subject 924.(I couldn't find the original audio so this pmv(not mine obviously) was plan b)(also spoilers for my book)

The head cannon is, what if after going crazy in that place Lightning somehow forgets about Snowy and their past. But Snowy still remembers and she remembers when they were kits  and she asked Lightning what happens when you die.(you forget everything)

She remembers back to the day when Lightning got captured. They were just playing around that day. But no matter how much they fought, Lightning and the others were taken.

So basically since when you die you forget everything. Lightning has died.(metaphorically)
