In Inca Mummy Girl, we see a scene showing Cordelia and Devon walking out to Devon’s van. Cordy’s exchange student, Sven, tries to interrupt the two and Cordy says to him, “Sven! Momento! Needa!” If you look behind Sven, to the left, as he reacts to this, you can see …

There’s a nice little scene in Passion where the gang’s research mode is interrupted by the unexpected appearance of two students (including Jonathan) looking for books.
