This film is FULL - and I meAN full - of parallels between Thorin and Bilbo and Kili and Tauriel. THERE ARE SO MANY I HONESTLY CAN’T REMEMBER THEM ALL??? Not to mention the few that were in ‘Desolation’. And believe it or not, this might be the most important factor here because these films are painstakingly edited and quadruple checked for every imperfection. There’s always last minute changes if the director doesn’t like the way someone’s freaking makeup looks in a 3-second shot. SO, it was a conscious decision to have these parallels. You could perhaps pass off the ones in ‘Desolation' as coincidence, but 'Five Armies' constantly jumps the audience from similar scene to similar scene between these two pairs. [SPOILERS] Bilbo and Tauriel have the same reaction when they realize their partners are in immediate danger from the trap set by Azog. Bilbo and Tauriel both tell off people who try to prevent them from going after their partners (Gandalf with Bilbo and Thranduil with Tauriel). Then later, we have Bilbo grieving over Thorin’s dead body, and then they cut right to Tauriel doing the same thing with Kili. YOU CAN’T tell me this is a coincidence. Peter Jackson wanted this, he wanted the audience to feel some sort of correlation between the two pairs of characters. There’s a few other small parallels to be found, but those were the huge ones.
