Ohh this was excellent, super intriguing, Naarel! I love how even though there are deeper mysteries and lore at play with the cult, fundamentally it's a story about two estranged sisters. The dialogue and writing in general is SUPERB and so realistically written. I can appreciate that both choices lead to the same conclusion - it does hammer home the fact that, no matter what Cassidy says, nothing will change. As an O2A2 entry, I also appreciate that you didn't use a sprite! It really emphasizes Cassidy's loneliness, as if she is all alone in the subway.
(Cannot believe that the follow-up to this is Shibboleth dgfdfgdg)
