@marie you're all missing the point. Sol fell in love with Brian's soul, which is literally defined as: "a person's moral or emotional nature or sense of identity." Even if Ian doesn't access the memories of his past life, he still lived it. That was still him.
Think of it as if someone lived a life and then got amnesia and lived another completely separate life. They're intrinsically still the same god**** person, they just have different memories and experiences. You can't just negate a person's entire past because they themselves don't remember it.
