The night before the battle.

Dwarves in the Lonely Mountain: build fortifications, put on armor, choose weapons.

Meanwhile, Bilbo and co. in Thranduil's camp tent:

Thorin: I will have war!

Thranduil: attack!!!

Me: [working in my garden and leaning over to take a closer look] so what we have here? Are the pixies back from the forest and terrifying my garden dwarves? The poor fellows just kicked that lizard out of their house and now there’s a new misfortune!! And what is this tiny creature with furry feet that they brought with them from their walk?

AU. Everyone is alive and living happily in Erebor. Bilbo and Tauriel plant a wonderful garden on the side of the Mountain and every day at 4 o'clock they drink tea there together.

On one of these days.

Tauriel: how funny it is now to remember how jealous Legolas was of me.

Bilbo: *takes a sip and looks into the distance* it’s possible that he was simply offended that the dwarves were interested in you, but not him. 

Tauriel: well, not everyone can turn the heads of dwarves the way you and I can.

They look at each other with smiles and clink cups of tea.

Meanwhile somewhere in Mirkwood.

Legolas looks at the portrait of Gimli in the medallion he took from Glóin.

Legolas: one day I will find you, beautiful creature.
