Besides the HELP button thing, little old me would like to clarify something.
The SOULS I had didn’t immediately turn against me. It was when Frisk communed with them that they started to awaken, and even then, it still took a while.
Sure, the SOUL I have in me right now is an exception, but that doesn’t mean that it’s going to instantly give Shifter a hard time. If you worrywarts are still paranoid, I can take the SOUL for a test ride to see how it affects me.
I’ve never had a perseverance SOUL in me for very long!
