Reylo Happy Ending Headcanon:
They settled down in ach to.
Found pure balance within themselves. Just like ach-to: powerful light, powerful darkness.
Kylo fished. Rey milked the creature. They never grilled porgs…
They domesticated the sea monster. Turned out Kylo was good with creatures(like Ezra).
He taught Rey to swim properly and she got better at it than him.
Chewie came to visit them every month with new supplies. And R2 stayed back to help around.
On rainy days Rey and Kylo would move to the high temple to keep dry.
The caretakers did’t mind them anymore. They were over the moon when they realized Rey was having a baby and since then they warmed up to her. They even helped during the child birth and aftercare.
Rey and Kylo had a couple of kids, one boy and one girl.
Ben dropped the name Kylo the day their son was born.
When their daughter was born it rained and stormed for 3 days. They knew that day she was going to be very strong with the Force.
On their 5th anniversary of moving to the island Ben asked Rey to marry him. Even though to them and in the force they were already married. But he wanted to give her a ceremony.
And they lived…. for years and years, on the island, happily. Until the time came to be one with the Force, together….
