Leave it to Hermione to take over. To always know what to do and when. Hermione wouldn't stay in bed with the covers pulled over her head. No, she would have already come up with a plan of action, something that would amaze them all, something that would prove what happened actually hadn't happened, and then...
And then...
And then what?
"Yeah, I'll have some tea." Eating was probably a good thing right then. And if she didn't eat, eventually mum would force the issue, and she just couldn't deal with mum right then. "Maybe some toast."
