I've applied the leftovers to the characters. @TheGenerator, Gertrude's Heartache track filled up, so you should black out a single word from her "Facts About Me" section. @Legendary_Sidekick, Amelie's Aeronaut track filled up, so you should take somebody on an adventure above the clouds. Once the track fills up a second time, we can do that again and then complete the journey.
We now have 1 square and 4 circle mementos. We can choose a new chapter to play or unlock things on the shelves. Or, if we're ready to try to fix Gertrude, we can convert some of the circles to squares and use 4 of them to track down Monday.
