I bet the 3 final ends can be Ciri saved, Ciri on the other side and Ciri dead. Some of the differents states can come from our decisions with these to women, among others (decisions, of course)... I'm off topic, am I not?
I bet the 3 epilogues involve 2 girls and one messed up relationship. It fits pretty well, no? :hmm:
As for Ciri, wouldn't "saved" and "on the other side" be the same thing? I can't imagine her sticking around, unless... she's finally ready to rule.
