here's a little post S5 TLK (we all know it's coming) speculation fluff for you...
Her lips, still tingling from the magic, press into his neck as she collapses fully into his arms. Her fear of being ripped away again clear in her fierce grip around his back, "I'm sorry" and "You saved me" escaping her lips between sobs, making him want to kiss her again to stop her from falling further apart.
Keeping his hook securely around her waist to support her failing strength, he moves his head back slightly, leaving light kisses along her cheek until he is nose to nose with her, silently imploring her to open her eyes and look at him. When her eyelashes slowly flutter and her teary eyes meet his he almost breaks, the vibrant green looking back at him so full of life and love that he silently vows to protect her from darkness ever touching her again as long as he lives.
Tracing the tracks of tears from her skin with his thumb, he smiles softly at her, coaxing a small smile in return with a upturn of his eyebrow.
She moves to speak and he shifts his thumb to cover her lips, shaking his head slightly.
"Sorry Swan, it's my turn."
Seeing the slightly defiant narrowing of her eyes at being shushed he knows that his Swan is back, his fears of never seeing her again finally fully escaping his tired bones.
Parting her lips slightly with his thumb, he leans in close until he is a breath away from kissing her, but far enough to keep her gaze firmly locked to his.
"I love you, too."
His mouth finds hers before she can respond, her breath escaping against his lips as he loses himself in her, caring naught for the onlookers waiting for their turn to welcome The Savior back home. Her hands reach up to cup his face, trapping the tears he didn't realize were falling against her fingers, her lips strong and sure as she returns his kiss just as passionately. They cling to each other there in the street, holding on to this good moment as long as they can before reluctantly pulling back, knowing she has others who love her just as much she needs to see.
It's only later, sated and wrapped up together on the verge of sleep in his cabin, does he find the courage to whisper his request to her in the blissful quiet.
"Swan?"
Snuggling closer into his chest, she mumbles a quiet "Hmm?" against his skin.
"I love you."
"I know. I love you, too."
"Can we vow to tell each other this every night?"
Her head shifts slightly until he feels her chin dig lightly into his chest, her eyes searching for his in the dim candlelight.
He sighs and closes his eyes, trying to find a way to explain his reasoning for this, too many memories of those words being the precursor to loss and pain. The sudden warm touch of her hand on his cheek soothes his haunted thoughts, the gentle press of her lips against his a comfort he wasn't sure he would ever have again after centuries of loneliness. Her kiss is soft and slow, telling him that she understands without words. There, in the quiet of the early morning, a silent vow is made, a promise to speak of their love often, a love strong as the magic that binds them… forever.
