Right, I wrote this because Tolkien never says anything about elves drowning. He says they can die in battle and of broken hearts. And I was bored, so we get.

Elves Can't Drown

. "You're sure he's alright? He's been under there for an awfully long time." Gimli asked Aragorn, peering into the water to see if Legolas' body had floated to the surface yet.

"Gimli, elves cannot drown. They have the ability to breathe underwater." "What?!"

Aragorn sighed. He could see he would have an interesting time explaining this to the dwarf who had decided that most of what he'd heard about elves (e.g. they ate their children to keep the birth rate down) were dwarvish myths. "Legolas told you that elves were immortal, did he not?" Gimli nodded, looking mildly interested. "But that they could be killed in battle, or die of a broken heart?" Another nod. "Well there's your answer! People who drown are dieing neither in battle, nor of a broken heart." "But. how do they breathe under water! Do they have gills?" "Well- yes." Aragorn laughed under his breath, remembering the day Elladan had shown the young human the gills on his ankle, and the fuss he had raised after. It was one of the funniest things Aragorn had ever done, even though he'd never admit it to either of his brothers.

Gimli's eyes widened and a thoughtful look overtook his features. After a moment, he said, "No, it couldn't be." "Whatever you say, my friend."

Legolas surfaced near the middle of the lake and began to wade in. "No fish." "Gimli doesn't believe that elves have gills." Aragorn said slyly. "Could you show him?" Legolas pulled up his sopping trouser leg, just enough to reveal a ribbed patch of skin above his ankle. "HOLY COW!!!"

End

Now, if you read this, you're probably wondering why I wrote it. Tolkien never said that elves could drown. By the way, I don't own Legolas, Gimli, Aragorn or Elladan. Wish I did, though.
