All things considered, Hermione is quite glad that time-turners don't exist anymore. Traveling through time had been exhausting, especially when you had to avoid your past selves even while attempting to keep them from doing anything stupid. Harry had very nearly broken that first rule of time traveling, and he'd been with her; she can't imagine what kind of havoc might be caused by someone with less sense or restraint.

That small grimace makes Hermione tense, wondering if she'd touched on something of a sore spot. But then he explains, and she finds herself needing to resist the urge to laugh, even if she wouldn't necessarily be laughing at him.

"Are you saying the thing you hated most about time traveling was having to wear clothes appropriate to the period?" she asks, unable to keep just the slightest chuckle from coloring her voice. "I don't know, I think that might have been part of the fun. It's not as though you can stand out if everyone's dressed in the same style, can you?" She pauses for a moment before bringing up, "Unless the Doctor had no idea what was period-appropriate at the time and would just throw things together from some sort of costume trunk he had in the TARDIS?"
