"Oh, is that..." It was rather difficult to look past the fog, but yes, the two people up on the tree seemed to big to be students. Teachers, then, and, well, one of them was flying, so who else could it be but, "Ms. Hargreaves?"  

Lyra registered the rest of the scene a moment later. "Oh, oh! Are you two having a moment?" she half-whispered. "And is that Mr... err-" He looked familiar. Must be one of those she saw during the speech? The name, inexplicably, came to her. "Mr. Manilow? Ooh."

You wouldn't be able to tell just by looking at her that Lyra was into [i]scandal[/i], and she wasn't, really. She was, however, excessively curious. Her interest was more of an academic nature, sure, but the questions forming in her mind were worthy of a blackmailer. [i]Are you two really a thing? Is the principal okay with this? Does anyone else know about you two?[/i] 

"Do you think the other teachers know about this?" she whispered, quiet enough that only ShiZen could hear her. "Do you think... hey wait!" 

They were here to find whoever had been shooting water at them, right? Okay, but it can't be either of these teachers! Ms. Hargreaves' a wind elementalist. Mr. Manilow's an earth elementalist. And there's no water gun anywhere! No, it can't be them.

She told ShiZhen this reasoning. "And I'm not letting those water squirters go. Come on, let's look for [i]them[/i]." Before she walked off further into the fog, she called out to the pair of teachers up in the tree, like an afterthought, "Sorry for the interruption, Ma'am! Sir!"      

The blackmail materials had already wobbled off her mind.
