Captain Swan kids Picture
So I had this daydream where Emma and Killian are asked by the Blue Fairy (she's involved in everything) to meet her in the woods. When they get there they're introduced to two girls who claim to be their daughters from the future and they have their big brother's storybook to prove it! Obviously Emma doesn't believe them because after everything she's seen time travelling is still a big no. But Killian's sure they're telling the truth, especially when they do their father's trademark eyebrow raise.
On a serious note I REALLY want them to name their first daughter Odette; because then she'd be a literal Swan Princess!
