Episode Description: To stop the POGs’ prediction network, Max and Molly realize they need help—and fast. However, they are torn on whether or not they can trust Charlene.  To test her honesty, they recreate an experiment with a “lost” wallet stuffed with cash.

Episode Description: Summoned to a High Tribunal – Max and Molly must defend their claim that a Mole has infiltrated The Order of Problem Solvers. After passing a high-pressure test, they argue their case—but nothing goes as planned. But in a twist, they discover that nothing might actually be the answer to their problems – and that perhaps the best Mole… is no Mole at all!
