The Hobbit - Battle of Five Armies SPOILERS!!!
The (wishful) follow-up to "One for the Road" - Everybody lives (the brothers at least), and at the victory feast/mourning feast for Thorin (since he'd probably still die in any scenario :/ ), Kili and Tauriel see each other again for the first time. They probably caught glimpses of each other in the immediate wake of the battle, enough to confirm the other is alive, so this isn't the tearfilled relief sort-of-scene. It's a more silent, glad-we-both-made-it moment.
Tauriel must've borrowed a simple Laketown-dress for this which is all good and well since she isn't royalty, and doesn't strike me as the person for pompous dresses anyway (only agreed to this since her battle garb got all dirty and blood-stained, and it's enough to take anyone's appetite away). Kili of course had Erebor's arsenal of clothing to rummage through^^
Both still look a bit battered, with scratches, Kili's leg in a splint and Tauriel's hair singed from Smaug's fire (I began this in January, long before BotFA came out).
</fantasizing>Kili (the Hobbit) is (c) J.R.R. Tolkien
Tauriel and the characters' design are (c) Peter Jackson
(Kili looks waaay too young, even by his standard...
