The Substitute (Glee)
Kurt rejects his best friend Mercedes Jones (Amber Riley) in favor of his new friend Blaine Anderson (Darren Criss). Mercedes does not like it when Kurt tries to set her up on a date with a football player because they are both black. She also feels left out when she comes with Kurt and Blaine to dinner. This is because the conversation is mostly about gay issues and icons. When Sue starts a healthy eating program and says people can not eat "Potater Tots", Mercedes starts a student protest. She also puts Tots in the tailpipe of Sue's car.  This causes $17,000 worth of damage.
