Mother (Doesn't) Know Best

Cas' mother is on a mission to find her son a boyfriend, but she takes things a step too far when she downloads the Grindr app. It's embarrassing and he can't seem to get her to back off and stay out of his personal life. Good thing his best friend Charlie just happens to know a gorgeous, nerdy guy that's right up his alley.
