She's definitely not going to have time left on her first Comprehend by the time they get to a library and/or university, then. She'll find a nice solid chunk of wall to put at her back and people-watch in the meantime. (And pull out something to read for when she gets bored of people-watching.)
...actually, if there was ever a time for some hedge-divination, it's now. She closes her eyes and riffles through the pages of her worn Book of Magic, stopping somewhere more towards the end than the middle.
...thus we consider a Sheafe of Wheat, with many Stalks mutually parallel, each Stalk in the shape of a Cylinder, and thereby touching one another in a series of Lines, a Section through this Sheafe being then as Circles upon a Page and the Points at which they touch. Therefore we consider the Section to be a Microcosm of the Whole, as the large and small ever reflect one another, until such a time as a Stalk may Branch, and thereby alter the arrangement of Points and therefore Lines. We now consider how one may determine which such Arrangements may be equivalent to one another...
Well. Sheaf of wheat is probably a good sign? Very Erastilian. And the part reflecting the whole is a common enough theme, but it's an innocuous one compared to some that could've turned up... probably it doesn't mean they can just strike a tuning fork using her coat or something, she's pretty sure that's just a rumor and if it wasn't it would make more sense for it to only work on outsiders and not messy complicated mortals. And hedge-divination doesn't give you that kind of answers anyway, not unless they were already in your head. (Now she remembers why she doesn't usually try it.)
(She's not especially hungry but she'll take whatever's on offer that's Not Worldwound Stew and doesn't have suspicious bits.)
