Now Daphne's heart was racing. On three they'd climb?! With what? There was nothing to grab onto up there! She looked at him through the scaffolding, wide-eyed and incredulous, but too afraid if she objected he'd try to go on without her. Daphne didn't trust anyone to not screw her over, especially when things were going badly. People got stupid when they were scared, and he had to be scared.
And yet if she didn't try, her hands would give out eventually anyway. There was nothing for it, push on or go down. Or fall down. So she screwed her face up and forced a little nod, wanting nothing more than for this to be over.
