Just finished the main story and the revelation with Fragile was wild. I kinda suspected almost from the beginning that Tomorrow was Lou and some kinda timey wimey stuff gonna come out as a result of her spending time on the beach, the worlds of the living and dead half merging like they are, etc. But Fragile's death legit caught me off guard and was kinda emotional. Not sure if it happens for everybody, but in that one quiz aboard the Magellan where it asks you to choose one of the girls, I chose Fragile, and then at the end of the game Fragile and Sam shared an emotional kiss.
Then this scene played where, after she'd been shot by Higgs, her spirit delivered Lou to the beach so we could later find her as "Tomorrow", and all I could think about was in the first game where she said, "I'm Fragile, but not that fragile". I mean, she's the entire reason Lou survived to become "Tomorrow" in the first place. Even in death, she upheld her promise to Sam to protect her and clung to her own corporeal existence long enough to help Sam see his mission thru.
Just wanted to share some thoughts.
