Hermione knew that no matter how much she wanted to just pretend like the previous day didn't happen, she couldn't. Rodolphus would be too suspicious if she just emerged from her bedroom and tried to act like they were back to normal too soon. He'd threatened the safety of her only child. That wasn't something that could just be easily forgiven. As much as she might have wanted to push through her mission to uncover the truth of his treachery from him, she knew she had to be patient.
