Thranduil, at least, had a great deal of practice in dealing with this situation, though recently he had not been called upon to use it. It appeared that was set to change.

That was Legolas, or a very close imitation, and so after some small consideration Thranduil made his way down the hall, in manner perfectly oblivious to the tiny being peeking out from behind the curtain... until he was level with it. Then he had pulled it away and was crouching, more or less on eye level in the space of a breath.

"Legolas." Despite everything, he is slightly surprised to see it confirmed.
