Code Words and Doppelgängers

Walter nodded, his smile never wavering. "That's alright, Ms. Thompson. The principal and I were just... finalizing some details about the upcoming dance." He paused, then casually dropped the code word they had agreed upon, "You know how important the 'night sky' is for the decorations."

The apparent Ms. Thompson smirked for a moment, then responded with the agreed-upon reply, "Yes, the 'stars' have to be just right."

Walter's mind raced as he processed the response, a triumphant smirk playing on Alison's lips. Gotcha, he thought, his partner-in-crime's identity confirmed. He had to hand it to them; the timing and execution were impeccable. Now, two transformed people were in on his game, and the principal was none the wiser, especially about 'Ms. Thompson's real identity.
