||SPOILERS FOR II S2 EP 16-18!!!||

It's been a couple months after Cobs' assasination, and life has presumably gone back to normal. The hotel was (mostly) rebuilt, broken bridges have been restored, and everybody feels free. But not Paintbrush. They feel trapped. They don't know why they stick around anymore. They feel the world would be better off without them. So, they stop coming out of their room, stopped eating, and stay in bed most of the day. They're on the breaking point.
Lightbulb is happy that everything seems to have gone back to normal. Finally, life can go back to normal! She can hang out with her friends, hang out with Baxter, and make as many cookie pizzas as she pleases! But, she's noticed a cloud forming around her flying buddy, Paintbrush. At first, she just thought it was a mood, but now, she's getting concerned, and now, their feelings and attitude have been rubbing off on her...
Test Tube and Fan, now roomates in the hotel, have been pursuing and evolving in their passions. Test Tube has started studying in the world of history, and Fan has been pursuing writing and creating music. One day, when visiting Lightbulb and Painty, they notice that Paintbrush keeps themselves under the cover of their bed, barely ever getting up. And to top things off, Lightbulb has also been acting odd, covering for Painty for every minor incident or issue. They want to make the situation better, but how can both of them combined help the two people they've gone through so much with?
(SORRY FOR THE LONG INTRO!! And no cover for now, I'll add atsome point, trust!!)
