You are the one that has best interpreted the internally focalised narrative of the first half. You bent with mastery the omniscient narrator presented by Gaby to your purpose. We readers step in the trap and unavoidably end up watching the action trough the protagonist's eyes and being transfixed with her in front of the final revelation. Timeline B is truly cute and bon ton, but you know that it's too sweet for my sick mind 😜 What a fun idea btw!
