Here's another thing that's interesting to speculate about
the game has implied multiple times the character are stuck in a time loop, the reason Ms.Grace could predict everything in 2.4 is because this wasn't her first time living through the event of 2.4 and Vertin claims that "she has Deja Vu" when reaching Antarctica
If Sonetto knows they are in a time loop that doesn't end well for Vertin, It's not unreasonable to think that the actual plot of Reverse 1999 is the same as the plot of Madoka Magika (Collab when?)
