Killian watched as Emma went up in the elevator. He watched as his future, his happy ending went on without him. He lied to her, he promised that she wouldn't be his unfinished business. He couldn't help that his unfinished business was never getting to live in that house he picked out for them. Or that he never got to marry her. Someday maybe have kids with her. Grow old together. He loved Emma swan and she was his unfinished business because he never got to do any of those things with her. But he was going to move on from the underworld but not like that, Killian was going to go with his swan no matter what it takes. Killian waited a long time to go up the elevator he wanted to make sure she was gone he couldn't take saying goodbye again. When he was back on ground level he went to grannies or the underworld fake version of grannies where he ran into Arthur. The man who killed him in the first place. Arthur and Killian then began their journey to defeat Hades. After Killian got the pages to Emma he knew she defeated him, a light opened for him to move on. Killian didn't know if he was ready to move on but he walked into the light anyway. When he walked through he was greeted by a man named Zeus who thanked him for helping defeat Hades. Zeus took Killian to where he belonged. A bright light flashes and Killian was standing behind Emma "swan" Killian said. Emma couldn't believe her ears she thought her mind was playing tricks on her. That she's finally gone crazy. Emma slowly turned around scared that it was only her imagination. "Killian" Emma whispered running into his arms. Killian and Emma did eventually get married, they soon after had a little girl named Hope. They grew old together loving every moment of it the good the bad everything.
