Spy vs. Spy

Jail Cell: Part 2 (2x12)

:

While Spy (still in jail) receives a cake from his mother, delivered by Black Spy, who is guarding him. It contains a nail file which White Spy slips underneath his cell to Black Spy along with a picture of an open cell window. Thinking White Spy escaped, Black Spy attempts to dive through the "open" window and gets knocked unconscious, allowing White Spy to escape prison successfully.
