To get one thing straight, Aurora didn't like Hook. She hadn't liked him at the beginning, when they met in the Enchanted Forest, when he was a villain, and she didn't like him now, even though he was a supposedly reformed person.
She respected Emma Swan. She was the sheriff, she was the daughter of Snow White and Charming, and she was royalty. If they had been in the Enchanted Forest, Aurora would have campaigned for the marriage of Emma and another royal, not Emma and a pirate.
But she had to, albeit grudgingly, admit that Hook and Emma were a good match.
She was strolling baby Philip through the streets of Storybrooke when she saw them. Emma was walking down the street toward her yellow driving machine, and Hook was leaning against it, a coffee lifesaver drink in his hand and another resting on the driving machine. When he turned and saw her, a tiny grin burst over his face. Emma smiled in reply and took the coffee he offered.
They kissed quickly, their grins only getting brighter, and then walked down the street, arms wrapped around each other.
They were adorable. Aurora couldn't deny it. She watched as they strolled down the street, focused on each other, probably talking about something or another. Eventually they reached the library and Killian kissed Emma on the forehead before watching her walk down the adjoining street.
Aurora couldn't stop the grin. Fine. They were perfect for each other, almost as perfect as she and Philip were. Not quite, of course, but close. She was willing to bet, not a lot, of course, since there's only so much money a former prince and princess in a new land can earn, that they'd be true love.
The princess and the pirate, Aurora mused as she kept strolling baby Philip along. Not traditional, but certainly not impossible. She kind of liked it.
