He hadn't objected, which Katara took as a small victory. He also, however, hadn't had quite as much enthusiasm as she'd hoped for. Although she did admit that could be due to his being tired, or possibly even the lack of the sun itself, more than any real feelings he might have for or against her plan.

"Wait." Lowering the cup, Katara's eyes narrowed slightly. "Did you just say Sarah would de-limb you?" Her brow furrowed before she shook her head, deciding maybe it was best if she didn't know the answer to that. Not that she couldn't understand Sarah's warning, but Zuko wasn't completely helpless without his bending, either.
