Episode Overview
K.C's socially awkward brother introduces a stunning girlfriend, but K.C suspects she's a spy. Desperate to uncover the truth, she resorts to extreme measures like handcuffing her to a chair and using a 'tickle-taser.' When these tactics fail, K.C pretends to have a covert conversation on her spy bracelet about retrieving 'important files' from her school locker. Misinterpreting this as genuine, Jolie follows her to school, leading to a confrontation where K.C uses gas from her bracelet to incapacitate Jolie. Discovering that Jolie was only interested in Ernie for intel, K.C persuades her to tell Ernie she's leaving for space training. Jolie departs for good, and K.C reconciles with her brother, proudly displaying the earrings she took from Jolie.
