It was about the 5th time Kris and Susie had visited the Dark World, but Kris has been acting weird all day. Holding their head like they had a headache, muttering something about 'files' and 'fakes' during these little twitchy episodes, and then going back to normal for a few minutes after a more violent shiver. It didn't make any sense, they had been completely fine before today. If anything, they should be happy since Asriel was visiting in 2 days. But they acted jumpy and terrified of every little thing, then denied anything was wrong. Something was quite obviously wrong with them, and it's up to you and the rest of the Fun Gang to fix it.
