Hermione would have elbowed Ron herself if Harry hadn't been there first. But Harry's agreeing to the baths made more sense than just a classroom, at least. Once you were in no one could come in until you were finished... kept anyone from accidentally barging in during a bath. And she thought the portraits there could be trusted.
She shrugged, not pushing it any more than that, and started that direction. At the door she mumbled her own password and let the two of them go in ahead of her. It wasn't until the door was closed and the map was out between their benches where they could all keep an eye on it that she started.
"So, Harry. Godric's Hollow..." But she didn't really know how to bring up actually going to the place where his parents were murdered.
