A/N: The prompt was "Killian! What the hell happened to your eye?". This is like I imagine this conversation to go, also providing a bit more closure than we got on the show.
"Killian! What the hell happened to your eye?" Emma asked when he walked into Granny's, looking rather pissed.
"I had a little encounter with our dearest Will Scarlet, who was still looking for payback. I guess I deserved it."
He sat down next to her and Emma reached up to turn his face around so she could see it.
"Let me see." she said and touched the bruised skin around his eye with her fingertips. He flinched and Emma let go again, sighing deeply.
"Well, he definitely didn't hold back. What did he want payback for anyway?"
Killian said nothing and Emma raised an eyebrow as realization slowly dawned on her.
"Wait. You were the one who punched him? After our first date?"
He let out a breath and averted his eyes. "I'm sorry, love, I… I don't know what happened. It was my bloody hand. The crocodile told me it was cursed because it belonged to my past self and - " Emma quieted him by pressing her lips gently against his. She caressed his cheek with her hand and gave him a soft look.
"Hey, it's okay. I know you're trying. Just… please tell me next time something like that happens. I won't hate you just because you punched someone who kinda deserved it. Okay?"
Killian nodded and took her hand in his to press a gentle kiss to the back of it. "I guess I just… well, I really want to be better for you, Swan. And I'm so very sorry that I didn't tell you earlier."
"I know. But Killian, just know that I… I could never hate you."
Emma gave him a small smile and he smiled back, tilting his head slightly on the side.
"Well, you did once." he said.
"I didn't. Not really. There were times I wanted to punch you - and I did. But I never hated you."
His smile grew broader and he reached up to brush a strand of hair behind her ear, before he leaned in and brushed his lips gently against hers.
"I bloody adore you, Swan. You know that, right?"
