Spending another evening alone inside her Hogsmeade home would likely drive her even further round the bend. Once she returned from her daily trip to Number Twelve to check on the progress of the potion that was the only hope she had for helping Dumbledore, she knew she couldn't bear to just sit in there waiting for it to be late enough to go to bed.

Much more harmful than the ones Antonin insisted she take to clear her mind, she knew that once she swallowed another, she wouldn't be able to stop. Not until she was dead.
