As they were resting; Yavanna and Tauriel were watching the young Hobbits training with Boromir and Aragorn. Which proved to be rather amusing, when they ended up tackling Boromir to the ground, shortly followed by Aragorn whom they tripped up because of his amusement towards the situation. It made Yavanna smile softly, at the merriment of the scene. The young Hobbits were willing to learn. But she couldn't blame them. They had to learn how to defend themselves eventually...especially on a mission like this.

"That's an awfully big cloud." Muttered Kili as he saw the large black thing in the distance. But for a cloud, it seemed to be moving quickly.
"I don't think, that's a cloud. It's moving too quickly." Yavanna said having spotted that aswell from where she was sitting. And surely enough. She was right. Not a cloud. Hearing the words of Legolas and Saeril, after that moment; she had helped urge everyone to hide.

Aragorn had quickly put out the fire, as he ducked into hiding; along with everyone else. Tauriel hid behind some large boulders, canoppied over with some trees, with two of the Hobbits and Kili. Yavanna ducked into the nearest bushes with Legolas. Whilst everyone had a hiding place of their own. Looking up, as they all waited for the spies to pass.
