oml you might've logged out before the full cutscene then. Look up a playthrough and skip to the end to see the deal with the cat!
Despite that though I still feel like it came out of nowhere. The s*icide was a shock but it made somewhat sense with the flow of the story, but the stabbing felt like a really rushed idea that didn't follow the direction the plot was going at all. Felt like more out of place than just the shock factor of the first ending. Didn't love it- I'd hoped for something more if i'm honest but nonetheless i appreciate the effort that went into making the game!
