Beleth clenches her jaw when Haldir gets after her about her pace. She can't tell him the truth of her pace, and more difficult still to justify keeping it after his biting words. But she's always been good at bullshitting.

"Forgive me, I was concerned for how my lady would take to being roughly jostled if you walked faster than our current pace. Clearly, I didn't think that it might be possible that you can't carry her for such a period of time." She starts moving again, this time at a fast clip, neatly hopping around the worst areas of muck. If that's how Haldir wants it, fine.

"But don't give up, if the burden is too much for you, you can try singing about it!" She calls over her shoulder, before scooting around a puddle. Even now she keeps her eyes trained to the ground, both to avoid the terrible field conditions, and to search for the ring. There's no helping it, she'll have to come back once Galadriel has been taken to safety and Haldir has...gone wherever it is he wants to go, as long as it isn't around her.
