Sighing softly, Daffy leaned back to look at him. She searched his eyes for something, anything that could give her something to convince him. Gently she slid her hands up to frame his face, holding his gaze. "I mean it." Daffy could only assume his argument with his brother had gone a little more intensely than this, but all she had was quiet assertions in the still of his workshop.

"You can figure it out, but not like that." She had to have faith he would be able to solve the potion problem without trying it on himself. "You need to be able to see the effects, not something you can do if you're the one who's unconscious." Daff tried to reason gently; she didn't want to fight with him about this, but she had to find a way to make him see that he could be trying out potentially dangerous potions on himself, by himself. "I'd rather you, well, maybe use me instead or at least make sure somebody is with you." Then at least he could see what was happening, plus she trusted him.
