Note: Alternate Timeline.

What if the story during "The Citadel" happens differently. What if Finn gains an incredible power of music and uses it to make peace with his past. What if the said power has a cost that Finn didn't expect. Well, the fun never ends, right? Expected a lot of song in the stories. Change Rating to M to avoid any problems. WARNING: The story is very DARK and Morbid.

A Bubbline oneshot inspired by the mashup duet "I'm My Own Problem" by Caleb Hyles and Ashe. Bonnie and Marcy get into an argument after having poor contact.

Revised 2018: Fionna and Marshall get close, perhaps a little to close one day and their adventures onwards creates a very interesting dynamic in an intimate way. Mature content ahead. 'Lemons' have been further 'removed', but still mature themes. Currently going through a refresh, please look at first chapter head and foot notes for more information. Thank you R&R xoxo.

“I’m just a hero. Not a friend, not someone who spends time with others, just someone who saves and protects the innocent. I don’t deserve to be loved or forgiven for my actions, so just think of me as a thing. Sorry Phoebe, but I can’t accept your love.” FxFP.

Marceline had really and truly thought she'd lost Bubblegum during the battle against Golb. Upon waking from a nightmare, PB is there to hold her and promise her that she's fine and not going anywhere. - Also published on AO3 -

Bits and pieces I removed from the original fic and made into little stand alone one shots. You don't have to read Educational, but in later chapters you might be confused at mentioned events/certain information. Other than that, these can all be read (kind of) as standalone one shots? I guess?

I hated the ending to adventure time, so i wanted a better ending with some closure on some story lines, with some romance, sorrow,and party bears!. Rated M juuuuuust in case, but shouldn't be anything worse than language.

Marceline sings song about her love.
