You know that moment when you felt like you were being taken on a wild goose chase through forests and fields and great canons and dry deserts? If the Gryffindor had been forced to walk much further she might have been feeling this. Legit. What were they trying to do? Find Neverland? And that giggling, Alexa didn't trust it. The last time something giggled at her she lost maybe three weeks of memory that she'd never regain and allegedly did things that she herself refused to believe.

What was Thompson onto exactly?

Lex wasn't in the habit of doubting Professors without probable cause and this here, was all the probable cause she needed. Someone needed to tell her where the giggling was coming from before she walked away from the class completely--though it'd be such a waste after having come all this way in the first place...

"Good day Professor." She greeted but her eyes never stopped looking around, just in case. Never know when an epic moment might happen given questionable circumstances.
