It's possible, I suppose. But I have a hard time thinking a traitor would fool a psychic, and it would damage morale if everyone started getting suspicious of each other. I'd say it's more likely that they got the information from a really tiny spy daemon, or by using mind-reading abilities on someone who knows there's a dance every year, or maybe they just found someone's syllabus that got blown away by the wind.
We can probably ask them after they're defeated and jailed for questioning.
