Yes, Val as a LI, meaning she gets an ending.
BUT...
I could mix all solo routes and all girls and possible relations and would get exactly what I tried to avoid. Endless renderings and branching.
So that's not happening. If she is a LI, she'll be one without Alex or Isa. But perhaps with a surprise
Well, if you have ditched Alex I'm sure the only time she want's to see you with another girl is in a BDSM studio.
And if you haven't, the only time she wants to see you is on your funeral, after she has killed you.
So no, on the Alex or Isa route there will be no Val.
(That's what the winter special was for, but let's talk about that in ... winter
)
