"I could," she said. She could leave it until the end, and it would be wiser to do so. However, her alternatives were to break into Malfoy Manor, which she knew little about and would bring up painful memories, or locate the Locket, which she was almost positive wasn't in the cave yet. Both were unfamiliar and daunting tasks. She and Aberforth had already retrieved the Ring with minimal effort. The Cup was what she was most comfortable getting at this point. It was a little ridiculous to prefer breaking into the most heavily-guarded place in the Wizarding world, but it was familiar. She'd done it before, and the security had been exceedingly hyped then. Unfortunately, her knowledge of its security was barely adequate for such a delicate mission. She'd tried searching in Keane's shop, but Goblins weren't much for writing books and wizards knew only of the alarms they triggered. Part of what made Gringott's so secure was the utter secrecy surrounding said security. This was for the express purpose of dissuading anyone from doing what Hermione and Aberforth were about to do.
