Short little one shot that popped into my head about Killian talking to Liam using the Ale that Merida gives him. Note, it is called the Ale of Seonaidh because that is the original name (Seonaidah is the land it hales from)

Make sure to check out my multi chapter fic Retrograde which was just updated the other day!

Enjoy

Thank you Brother

Killian let out a low sigh as he opened as he opened the container of ale and poured the last of its remnants over the makeshift memorial that had been set up after their stay in the Underworld. He stepped back, the now empty container that Merida had given him and Emma at their wedding a few years prior in his hands. The Ale of Seonaidh had been a precious gift from the Queen and now he was using what was left of it.

It did not take long for a figure to appear in front of him. Even though he had been the one to summon the person, it did not stop the gasp that escaped his mouth. "Liam."

"Brother." Liam said in a reassurance that he was actually there.

"I didn't know if it would work." He explained, flustered. "You had already moved on and the ale-"

His older brother cut him off. "Magic is not as black and white as you might think brother."

"I wanted to see you again." Killian breathed out. "One more time."

Liam nodded. "I see you made it back to your world in one piece."

The memories of his return to this world flooded in and Killian could not help but give a small smile. Even though it had been hard at the time and things did not go as planned, he was back and that was all he could ask for. "Aye. We defeated Hades and Zeus rewarded me with my life."

Liam hummed. "I assume Emma was much pleased. How is she?"

"Bloody brilliant as always."

"You finally buckle up and marry her or do you need to die again in order to make that happen?" Even after everything, Liam could joke about his situation. For that, Killian was glad.

"I asked six months after we got home and we wed six months after that."

"And children? Or did Emma have enough sense to not let you influence any tiny humans."

"You met Henry in the underworld. Fine lad he is." Henry and Killian had grown closer after their return to Storybrooke and he was thankful for his fatherly role in the boy's life. He knew he could never replace Neal and he never wanted to. He simply wanted to give to the boy what he and Neal both never got. "And than we had two of our own. Evie is almost three and Liam is a few months old?"

"Liam?' His brother asked and he could tell there was emotion caught in his voice.

"Aye. We thought it only fitting. Wanted him to be strong and brave like his uncle."

"Thank you, Killian." Liam smiled.

"Tell me brother," Killian took a step closer to his brother. "Tell me you are happy."

"I am. I can sail to my heart's content here. They don't call it paradise for nothing you know."

Liam's figure started to twitch and become like what Emma and Henry called static. He knew from what Merida told him about the Ale that it meant that he was losing the connection between worlds. "No-"

"It's alright brother." Liam assured him. "I'll be fine."

"Liam, you should-" Killian choked out through the tears that were starting to form.

Liam shook his head. "What's done is done. I am happy now and I want you to be happy to. Be a husband to Emma and a father to those children of yours. Give them what we did not have as children. Be the hero, Kilian. You've earned it." With each and every word, Liam started to leave more and more.

"Liam-" Killian yelled as the picture completely faded.

Killian stood in silence for a few moments, not able to move or speak. That would be the last time he saw Liam before he moved on as well. He had lived for such a long time without his brother and now, even though he knew that Liam was in a better place, it felt as if he had lost him again. His brother was happy though, in a place with no more pain or death, and that was all he could ask for Liam.

He took a step back on the grassy plain and looked at the tombstone Emma suggested they put in a few years ago to honor Liam. He walked over to it, placing his hand on the top before whispering one last thing to Liam.

"Thank you brother."
