Having Lila to stay late, or come later after class as a private session seems most feasible, at least in my opinion. Say that Madame Naumov has an early evening class; Lila could be in that and intend to stay late with her afterwards. That would give her an excuse to stay in her leotard. Or, the class could be a different one with Lila not participating, like a more advanced class, or a children's beginner course. After the class, she goes to change and stumbles upon the abduction.<br/><br/>Let's see what ambrosial has to say, since her character is involved.
