Killian rubbed the back of his neck in anticipation as he waited for Emma to return. He didn't like the thought of her going to see the Crocodile by herself, but they both agreed it was for the best. It was going to take a lot for him to adapt to this world as it is, let alone how he was going to live in this new world with his arch enemy living less than ten blocks out of reach. Killian paced the floor of the loft, trying to find something to distract himself. He stopped and looked at Emma's bookshelf, hoping to find something of interest. His eyes stopped on 'Peter Pan', and a small smile crept across his face as he pulled it from the shelf. He slowly paced as he read. It was a lovely story, not quite exactly how it happened, but enjoyable nonetheless. He didn't even get to the part about himself by the time Emma returned. He slammed the book shut and dropped it on the couch as he rushed to catch her in his arms, lifting her off the floor as he spun her around.

"Wow, I wasn't gone that long," Emma said as he placed her on the floor. He cupped her cheek then ran his fingers through her hair, like he was trying to convince himself she was there.

"I'm just glad you're okay," he said, breathing out a large sigh.

"I can handle Gold," Emma assured. "In time, you will too." She took the yellow potion out of her pocket and held it up for him to see. "He was surprisingly agreeable." Killian inspected it with his eyes then looked back at her suspiciously.

"What kind of deal did you have to make?" he said, worrying about her answer.

"Actually, when I told him what we did for his alternate-world self, he only asked that I start clearing my schedule for travel plans. Something about cashing in on the favor I already owe him. I guess I got a 2 for 1 discount," she said shrugging. Killian was not so easily satisfied. He felt like there was more to this coming, he was sure of it, but Emma was safe for now and that's all that mattered. Emma spun the bottle between her fingers as she lead him upstairs to her room.

"I always enjoy being pulled toward a lady's chamber," Killian said with a wink. Emma gave him a small swat as they reached the top of the steps and walked toward the mirror in her room. Killian joined her side as Emma reached up and sprinkled the potion over the mirror. It started to swirl with a yellow misty cloud, which settled and hovered around the edge of the mirror. In the reflection, now stood the alternate Killian and Emma, who did not notice their presence yet. They were both dressed in royal attire, no more in the torn clothes they used to wear. Hook cleared his throat and the two jumped as they realized they were not alone.

"What the bloody..." Killian said, then looked relieved when he saw their counterparts in the mirror. "You're alive!" Swan joined his side, and the counterparts were in reflective positions from each other.

"We just wanted to make sure you two were okay," Emma said.

"Everything is wonderful," said Swan. "My father and the kingdom is restored, we're back in the castle and Regina is locked up in Rumplestiltskin's old cell. I think we can finally have our happily ever after."

"I see you two might have yours as well," Killian remarked, noting Hook and Emma's stance. The two blushed at each other, then Hook grunted.

"Yeah, we found each other," Hook said, winking at Emma.

"Thank you for everything," Emma said. "We wish we could be there to thank you personally."

"And thank you, for saving our kingdom," Swan said. The mist around the mirror started to grow thicker and swirl once more, and Hook and Emma knew the magic was starting to fade.

"I think this is all the time we have," Hook said. "Be well, my friends."

"Farewell," Killian and Swan said together. Swan waved, and Killian gave one final salute with his hook. Once the magic faded, Hook and Emma turned to each other once more, Hook pulling her into his arms.

"It seems as though all four of us are fine," Killian assured, smoothing her hair as he held her.

"Yeah," Emma said, pulling back so she could look into his eyes. "I feel better knowing they'll be alright now."

"And what about us? Are we going to be alright," Killian asked, looking into her eyes. Emma reached up and gently kissed his lips, giving him a silent promise. Everything they promised before they came through the portal would be true. They were together now, no matter what would lie ahead of them, they would face it together.
