My Jolteon form is considered the real me and the others were masks I was wearing until recently and the Vulpix was me cracking for the real me to show through.
Kura found the masks not long after jolt showed but i seemed happier this way so she let it be until it needed to be brought up which it did recently since we kept hearing the voice but could not figure out where. She was projecting thoughts through the mask to us.

After some consideration i decided i don't want to hide myself after being revealed and i want the old Shay to still be themself... myself? Idk
So we make a clay mold with a bit of life like clay to have the mask take hold of.

So now we both exist.

The older Shay also can have a different masks be put on to change for to the ones she's been. I'm sure more masks can be made too.
But that's for later.

For now we do have both but I'm main front and me and her i assume are very linked. Will need a nickname for us both that isn't just shortened stuff though.

We've not been found of JS (Jolteon Shay) and SS (Sylveon Shay) and we are both still Shay so like. Uhhhh
