I am going to call this "non canon" since it's kind of "off the wall" very disconnected, just bonus ideas, etc.

It's just a little something I typed up because my brain began thinking of what they would say to each other in the afterlife. I am not even sure what the afterlife would be like with the Zelda games, I mean we get lingering ghosts (Darmani and Mikau in Majora's mask, Queen Rutela in Twilight Princess, Laruto and Fado in Wind Waker) but we don't know anything about an actual afterlife.

So…my brain cannot decide just what it is like either, so I will let you decide where they are and what they look like (ghost forms of their old selves, little flame spirits like you see in anime, you decide.)

"The afterlife is so boring…we don't even get to eat…" Sheik whined "Boy do I miss having taste buds."

"You and your food…just enjoy being a free soul, quit thinking about the bodies we used to have to take care of. I for one am glad to be free of the fuss of staying alive…" he paused for a second, what he just said was not entirely true…he missed life just as much as Sheik.

"I wish I could have fried up just one last skulltula…"

"Speaking of which… I cannot believe the things you made me eat!"

Sheik laughed. "I miss eating the most, but there other things I miss…like the warmth of the sun on my skin…"

Kakariko sighed "The smell of tea…"

"The smell of fresh bread…"

"The crunch of snow under my feet…"

"Getting the hiccups..."

Kakariko looked at him funny "Not getting the hiccups…"

Sheik laughed a little at that. "The thrill of a dangerous leap…"

"The wind under my wings…."

"…But…despite what we miss, I guess it's not so bad to shed the ol mortal coil…" Sheik sighed and looked around "This is nice, and peaceful, I have to admit that."

"I guess in life people are not too far off when they say death is eternal peace…"

Sheik was hardly listening anymore, his mind had drifted to something else "I wonder why my father is not here…"

"I may not know your father very well…but my guess is he's haunting your castle, protecting it from the Garo."

Sheik snorted "Now that you said that, I am almost certain he is! He is so stubborn, I bet that even in death he's still guarding the place…but, well if that's where he is, I guess he'd be content with just staying there…Buuut considering who else we have found here…my guess is everyone ends up here eventually."
He looked to Kakariko "And it makes me glad to know that I will get to see my mother, Renado, Riza and Trill again…someday."
Sheik paused and then coyly rubbed the back of his head "But not too soon I hope though, for their sakes!…But when the time comes, we will get to be a family again." he sighed happily.

"I will get to see mine again as well, I miss my family dearly…I cannot wait to see them again, and learn about what they did with their lives."

"My life may have been short, but I did far more with the time I had than most people."

"I can say the same."

Sheik laughed

"What?" said the winged soul

"That line again."

Kakariko's voice was sarcastic "Well then there is you and your 'I'll see you on the other side' you said that how many times…" his voice trailed off and became softer "…Actually…" he looked at Sheik "The last time you said that line…that was the best thing I could have ever heard at that moment in time..."

Sheik's tone was warm and happy "I know your voice was taken when Majora struck you…but, just as when we first met, your eyes spoke volumes more than your words ever could."

After a pause Sheik coughed as if to clear his throat, this was getting a little too sappy for his taste "Come on, lets see if animals end up here too. I would love to see my little dog again, Growler and I parted ways when I was still just a boy."

"Just please don't tell me he tasted like cuccoo."

Sheik stammered "Good gods I am not that bad!"

Kakariko laughed "I was kidding."

"Oh…"

They looked at each other and then snorted in laughter.

"I know you are not that bad."

"…well I will admit, I thought about it once."

"Sheik! Damn it! You'd better be glad you don't have a body for me to hurt because that's the last straw!"

"I was kidding!"

Kakariko glared at him

"Honest! I would never even think of it! …Now octorocks on the other hand, I would have loved to try one those."

"….Even without a body, I still feel like I am going to puke at the thought of that."

"You mean an octorock sounds more gross than a skulltula?"

"Oh, bleh! When you ate that one the night after we met! I think my stomach curled up and died!"

Sheik giggled himself into a full blown laughing fit. His laughter was contagious as Kakariko started to chuckle as well.

As they each calmed down Kakariko spoke "Meeting that day in the woods, well, in a way it was the beginning of the end… Once we crossed paths our fate was sealed…But, I am glad we met in life, because it meant we got to be friends, even beyond death."

"Ya know, death may not be so bad, but what we did in life still mattered a lot, it set up how we would spend eternity. I guess that is why we don't get to know what death brings, if we know it's like this, then we won't 'live' our lives…the uncertainty of it all, that is what fuels the flame of a living soul.

Life is a gift given only once, it is fleeting, and precious…its rich and wonderful, there is so much to experience before the time is up."
Sheik's voice was nostalgic and maybe a little sad "I don't regret giving up my life…but."

"But this is boring compared to life. Right?"

"The afterlife is so boring!" Sheik whined again.

"Your hopeless. Come on, lets go see if we can find your dog, it may take a while."

"Oh like time is an issue anymore." he scoffed "But, okay, looking for him might at least help me quit thinking about food."

Kakariko laughed, Sheik chuckled right alongside him.
