Marceline and the Dark Blue-Eyed Teenager

Following their experience in the Glass Kingdom, Marceline and Bonnie just want to relax. One day, she hears a knocking on her door and Marceline recognizes it: the voice of a woman she used to date, a girl with dark-blue eyes, which terrifies her. She is unsure what to make of this development, considering this girl disappeared on her after promising to be with her *forever*, afraid because she thinks this *other* girl is more pretty than Bonnie, who makes a bet of what will happen *if* this girl is prettier than her. It turns out that Marceline was right, but also it is revealed that this girl, who thought she was gone for a couple of months, was actually gone for hundreds of years, which completely devastates her. Can the girl and Marceline get along again... or will this cause strains with Marceline's relationship with Bonnie?

I was surprised to not see any fics with this ship already, especially since Olivia Olson voices Marceline AND Vanessa! So, this is the first one of that ship on here, from what I'm aware, and I may write others in the future, if you all like this one. I tried to respect the canonicity of bubbline here, because I love them both together. I've had this fic sitting there for a while and I decided to publish this now so it wouldn't be lost in the shuffle as I continue to go through my fic backlog. Height estimates from Reddit, although some say she is 6'2''- 6'4'' according to Reddit while summarizing some content from JAGM's complete Adventure Time Chronology. According to Vanessa's fandom page, she is 5'8" which is the same height as Candace Flynn!
