Ron turned suddenly to Harry. “Why can’t they help?”
“They can help.” He dropped his voice and said, so that none of them could
hear but Hermione, who stood between then, “We don’t know where it is, We’ve
got to find it fast. We don’t have to tell them it’s a Horcrux.”
Harry looked from Ron to Hermione, who murmured, “I think Ron’s right.
We don’t even know what we’re looking for, we need them.” And when Harry
looked unconvinced, “You don’t have to do everything alone, Harry.”
