Thranduil, dropping Elrond off at the airport: Have a safe flight

Elrond: I have no say in the matter.

Thranduil, already driving off: Die then

Elrond: If I died, how much would you miss me? 

Thranduil: It’s cute that you think death can get you out of this relationship.

One of my most deranged Silm headcanons is that Elrond and Thranduil were meant to have an arranged marriage. Look, Oropher was well aware that the reemergence of Elu Thingol's heirs might not be a great thing for his claims to the throne. The obvious solution? Marry one of them into his family! They were about the same age as his son, after all. And it had to be Elrond, partially because Elros had picked mortality and partially because Elrond had already been identified as the "nice one" of the twins.

It really didn't help that Thranduil looked a fair bit like Thingol (especially for an unrelated elf), Elrond looked a lot like Melian, and many of the old Iathrim were still really not over losing their first king and queen. So Thranduil and Elrond got engaged to great joy (from almost all of the Sindar) and great awkwardness (from Elrond and Thranduil).

Now, Oropher thought this was a marvelous idea! He could secure his claim to the throne, please many of his nobles, and secure some ainur blood for his family all in one fell swoop.

(The running rumor was that Melian had created Luthien via a magical ritual with her and Thingol's blood, so he wasn't too worried about the fact that Elrond and Thranduil were both men. They could just brew up some grandchildren for him with Elrond Maia powers, no problem.)

Eventually, Thranduil was able to talk his father own and convince him that the arranged marriage was, in fact, a bad idea; and that Elrond, in fact, had no interest in challenging Oropher's kingship.

So Elrond and Thranduil never got married. They did become great friends, though, and legally, the engagement was never dissolved. They still decide to be obnoxious about it sometimes.

Something Sleepless in Mirkwood

Fandom: The Hobbit

Relationship: Elrond/Thranduil

Summary: Thranduil is plagued by the shadow haunting Mirkwood Forest.

No - Thranduil is haunted by the War of the Last Alliance.

Or - Thranduil has succumbed to some new and unknown illness.

Whatever the problem is, Elrond must solve it quickly, for even immortal Elves may not have forever.

            “How is the pain?”

            “I had never said there was pain.”

            Elrond exchanged a long look in silence with the king, who was seated on the long edge of a divan in the little room.

            “I had assumed, as you had asked for this, that there was pain,” said Elrond after the pause merely continued to lengthen.

            “It is manageable,” said Thranduil. Elrond exhaled quietly.

            “Niwë says you are having headaches,” he tried. “Is that so?” If Thranduil was annoyed with the queen for remarking on his health to Elrond, it did not show on his face. On that day, he was crowned with a wreath of ferns and other greens, spotted with little white flowers, possibly young larkspur. His robes were greenish-gray and accented with indigo.

            “Yes,” he admitted.

            “And how is the pain?”

            “Manageable.”

            Elrond tapped his pencil lightly against the parchment. A bag of instruments sat nearby on the small, thin-legged table.

            “Have you noticed any patterns?” he asked. “A time of day, something you were doing when the pain struck, any other accompanying symptoms?” Thranduil was silent, looking over at a frieze on the wall, which depicted a sun-dappled woodland clearing, and then at last he said:

            “No. But I have been beset with dreams.”

            “About—?”
