Personal issues aside, she needed to figure out how to get the Cup. Bellatrix and Rodolphus were married by now, according to Sirius. They had been given Hufflepuff's Cup as a wedding gift, without being told what it was. They kept it safe all the same, in their Gringott's vault. In Hermione's original timeline she'd had a hair from Bellatrix, plus help from her boys and a goblin. This time she would have to come up with a plan that she could execute on her own. Hopefully she wouldn't have to escape on a dragon this time.
