@MagicBananas Look at it this way: The original game plot has gone incredibly off the rails. This information dump may have been part of the backstory all along, it's entirely possible. Because Endo and Kobayashi's influence has changed a lot of things, what we have now are people willing to work together to help Finne and her mother. (Especially since Rize-tan no longer has to isolate herself in her original negative emotions, so she is everready to throw down for Finne's sake)
Without them, it's likely that Finne and her mother would be screwed. Despite what little we see from Kobayashi spoiling the original plot, all that seediness about the Marcheners or whoever still exists. Just that they'd be bigger problems than what they likely will be.
