Swamped

There's an old woman glancing over a scroll. She's also wearing the strangest raincoat you've ever seen.

You manage to get enough of a look at the scroll to see that it's just random scribbles. A prop, most likely. On the other hand, she doesn't seem to be hiding it very carefully... but most people probably aren't as familiar with the characters of as many languages as you are.

Well, you don't see anyone else with reading glasses. You do glance briefly at a person with a very large-brimmed hat, but they soon lean back and you can see their face clearly. No glasses there. No other concealment opportunities strike you.

So unless the informant was playing games with you for some reason, the old woman is Evan. But you have to admit you aren't entirely sure.

Well, there's enough time before the show to strike up a quick conversation. Maybe you can better confirm your suspicions, or perhaps learn something of interest.
