However, hearing with her Elven ears that they were gonna search within a troll hoard, she did hear at the same moment that Kili politely refused to enter; Fili followed suite. After all, he and his baby brother were Thorin's best scouts and hunters; throughout their childhood, they have trapped animals together, and even trained outdoors together. The memory was a fond one, even to Saeril. Speaking of scouting, the she-elf waited for the company to proceed into the cave before mischievously looking at her youngest godson, approaching him from behind. "Hang on", she happily told him, before holding his small stature, and gracefully glided upwards with a flap of her feathered wings. After a few moments, they were perched in a tall tree, above the cave.
