This is a headcanon of mine and I hope they address something about this in the final two episodes! Picks up right at the end of 5×21 “Last Rites”
Storybrooke being what it is, Emma cannot count on anything more than a single quite moment with Hook before something else goes to shit – a death, a kidnapping, someone being sucked into a fucking portal. She clings to Killian with more than a hint of desperation as they stare at Robin’s grave and, pressing a final kiss to his stubbled cheek, she allows him a minute alone with the deceased thief.
They seemed to have a few things in common, her pirate and the archer outside the law. Emma will always carry the weight of Robin’s loss – and the layer of guilt inherent in that – but as for the loss of an ally and an understanding ear, Killian will feel his absence more keenly.
The other mourners have trickled away, leaving the funeral director the only witness to Emma and Killian climbing into her bug to head back to town. The drive is quiet, sweet, Hook’s hand firmly in hers as she navigates the familiar streets, and more than a few kisses on her palm, as though he relishes the privilege of just touching her.
This intimacy is new, but wonderful, and after the pain and the agony of the past several weeks since his death and the months since she took the Darkness inside of herself, she is glad to feel a Light blossoming inside of her that was never possible in the thick haze of the Underworld.
“Before you get mobbed at Granny’s,” Emma starts, taking the keys from the ignition, unbuckling herself, and turning to face Killian, “I want to give you something.”
“If it is more kisses, Swan, I would not protest.”
She gives him a glare that is more affection than bite, then grasps the chain around her neck to draw out the trinket that has rested against her heart since she first accepted it. With a duck of her head, she pulls the chain off of her neck and holds it out to Killian, where it dangles like a silver promise from another life.
