When Connie finishes her Mal Studies reading and goes to put the book down, there's something on her desk where it was mostly empty before. She freezes for a moment, squints at it- a stack of three little bronze coins, perfectly innocuous looking- pokes it gingerly with the end of a pencil- the top coin topples off and it doesn't otherwise move- and only then remembers that they get snack bar tokens. These are probably them? She pokes them again, pockets one and tucks the other two in her backpack, and heads out into the hallway. Not many people around this time of the morning.
"Hey, I think I got snack tokens? Anybody else get snack tokens?"
