"Words are meaningless without," Draco began, then stopped.   He wanted to say words were meaningless without something to back them up, but he had nothing.  The potion was still just an idea.  He hadn't told his father off.  He hadn't done anything that mattered. He tried to think of what to say and just settled on, "If it gets bad, you'll tell me, right?  Even if she doesn't want me there, you can sneak me in so I can set a hand on her in her sleep and make it better."
