FOSTER | LORELEI | LEO
As Lorelei said, there's really no need for apology. We weren't exactly forthcoming to the world about being Frank and Alice either. You're still Leo, even if some part of you is Neville too, you know? Like, I know in this life I'm 100% Foster and my choices here are mine, but I still remember everything about Frank even though I recognize our similarities and our differences. Dreaming about Frank has definitely shaped some things for me, but I don't really view that as a bad thing? I feel like I'm probably a stronger person for experiencing his life. I've learned a lot from him.
I guess my point is...it's still your life and your choices as Leo. Neville is just...a really great bonus, I think.
