YOU LEAVE MY LOVE FOR THE BOYS ALONE *cuddles*
Firstly, Dev, you know me, Tauriel would have none of the anything to do with shit. So, let’s get rid of that one right off the bat. *boots her into a shrub*
It’s a tough call. I mean, obviously we’re not being completely realistic so I can definitely See Fili giving the throne to Balin. He’s not ready for it yet. Maybe at least have Balin teach him the ropes for a few years. But at the same time, I think he’d feel uber responsible (at the sake of his uncle’s happiness) to rise up and take it.
Like “ok Uncle Thorin will be happier living in buttfuck whatever with Bilbo. Good. He needs that happiness. He’d be happier with him than here anyways.” So I think, maybe he’d consider giving it to Balin, and maybe even go so far as to discuss it with him, but in the end he’d totally feel responsible for it albeit a little frightened. And Kili would probably feel a little embarrassed perhaps at being a consort but in the end it’s not like anyone would really care I think. There’s a fucking Durin on the throne for a last hurrah cos I don’t think Kili would ever properly want to take it unless something happened to Fili in which case he’d only do so to take revenge (precious little beast ;3;)
Let’s just go with: Fili takes the throne but only with Balin as his right hand man to help guide him and Kili as his Prince/Consort.
EVERYONE LIVES HAPPILY EVER AFTER THE END CASE CLOSED BRING IN THE DANCING LOBSTERS AND CHINESE FIREWORKS
