[During their journey, Kili has had to get used to responding to Thorin telling him what to do, what to attack, when to attack, when to run. It's no surprise that the calling of his name seems to send him into action.

What his nephew figures out instantly has Thorin formulating a plan.]

Kili! Attack again, at the eyes, I will strike their under belly once they've reared back. Keep away from them, don't let them hit you!

[If they work together and keep out of the way this should be easy enough now that they've worked this out. When Kili does it again he'll swoop in for the kill, at least on one of them.]
