Juliana probably ought to have been more careful with what she said (she had a bad but at this point very much ingrained habit of making observations aloud), but as long as no one was passing nearby it wasn't as though there was any harm in it. Only someone was passing nearby, as it turned out; they were coming up behind her, and Jules hadn't even noticed them until they responded. Whoops. Luckily, she didn't seem to be a Muggle — or if she was, she was a very blasé one.

Probably the former, though. At least, Jules was going to work under that assumption until given some evidence to the contrary, she decided. "Well, whoever put that up ought to be careful throwing about glowing sigils."

It wasn't exactly subtle; it covered the entire brick wall of the side of the building. And while the glow wasn't blindingly bright, it was certainly steadier and lighter than anything that could be contributed to a glint of reflected sunlight. It looked as though it was in use, she thought — or at least, that was what the glow implied to Juliana. But in use for what?
