Hermione's visit to Ron's Hogsmeade home gave her more questions than answers. When she returned to her cottage, hours before Antonin as she suspected she might, she spent the rest of the day dissecting every single moment of the too-short conversation. Much more needed to be said. If Rabastan hadn't interrupted, she might have finally gotten the answers she needed to determine if she wanted to throw her lot in with her former friend or not. It was quickly becoming evident that she would have to pick a side. Trying to remain neutral or just outside the action wasn't going to be an option.
