The room representing her and Undyne in the third MANTLE game also raises questions. If you kill the silver fish the yellow dragons all kill themselves - so that's obviously Undyne and Alphys...but why are there FOUR Alphyses?

Honestly, it's more likely that Alphys is involved with whatever the fuck Gaster is up to. Also, why the fuck does the MANTLE room that represents her and Undyne have four Alphyses in it?

>all kill themselves if Undyne dies
She's working with Gaster alongside three other alternate versions of herself. Kris is pissed at her because 1. they know that she's responsible for putting the SOUL in them or 2. the SOUL knows that she's responsible for taking them from their own body and putting them in Kris.
