Once Upon A Mamma Mia Masterpost
Once upon a time, I half-jokingly made this post about an idea for a Captain Swan/Mamma Mia AU. And then I proceeded to write the first chapter hours later and it spiraled from there.
Anyway, this is a masterpost for links to each chapter of the fic, as I have finally completed it! This is my first ever completed multi-chapter story and I’m really proud of that fact. It was my first true venture into writing again after years away from it so I really enjoyed getting to work my creative muscles in this way after a lengthy absence.
If you’ve read this story, I hope you enjoyed it! If you haven’t, I hope you may give it a go one day! Once Upon A Mamma Mia
Chapter One: Honey, Honey (AO3)
It makes sense that, after finding Emma, Henry would start to have questions about his dad. If only they were easy to answer...
With Emma's silence on the matter, Henry takes things into his own hands and invites the three men from her past to his birthday party, determined to figure out which one is his father.
Chapter Two: Knowing Me, Knowing You - Part One (AO3)
A glimpse of three strangers in Storybrooke causes Emma to begin a trip down memory lane...
Chapter Three: Knowing Me, Knowing You - Part Two (AO3)
Nothing terrified Emma Swan more than the knowledge that if she took down the walls that so tightly guarded herself, she would willingly hand her heart over to Killian Jones.
Chapter Four: The Name of the Game (AO3)
With his potential fathers showing up in Storybrooke, Henry needs to figure out a way to identify which one is his real dad.
Chapter Five: Does Your Mother Know? (AO3)
Emma still isn't sure why her past has decided to visit her now, and all at the same time, but she's determined to get to the bottom of it. Meanwhile, Henry's determined to get to know his potential fathers.
Chapter Six: I Have A Dream (AO3)
Emma reunites with an old friend, Henry finally meets everyone in Operation Papa Bear, and chaos bubbles under the surface.
Chapter Seven: SOS (AO3)
Emma has to deal with the aftermath of Henry's stunt in Granny's, even if it means promising another meeting with the three ghosts of her past. But first, she needed to ground this kid.
Chapter Eight: Mamma Mia - Part One (AO3)
Much like Emma, Henry doesn't listen. No one else seems to want to find out but he needs to know who his father is.
OUTTAKE: the best things in life, the very best things, happen unexpectedly (AO3)
It's been ten years since they spent the night together on Halloween. But now he's back in her life and, despite the mess that's going on with Henry having three possible fathers, she can't stay away from him. Killian Jones was not a man that a woman could easily forget. [Rated M]
Chapter Nine: Mamma Mia - Part Two (AO3)
Dealing with Neal in the midst of a bar fight as Tiffany’s ‘I Think We’re Alone Now’ blasted through the speakers is not how Killian thought this day would go.
Chapter Ten: The Winner Takes It All (AO3)
Killian is making Emma feel better after Neal's antics but the guilt is weighing heavily in his gut. He has to tell her, even if it means losing her.
Chapter Eleven: Waterloo (AO3)
Oh yeah, Henry needs to get ready and Neal needs to be dealt with, but Emma can definitely do all of that before the graduation ceremony later that morning.
Chapter Twelve: Slipping Through My Fingers (AO3)
Henry was going to find out the results of the paternity test no matter what. He just hopes he likes what it reveals.
Chapter Thirteen: Thank You For The Music (AO3)
All adults want to do is talk and maybe all Henry wants to do is wish he never started this.
