When New Directions returned from nationals in the spring, Sam and Mercedes began secretly dating. But over the summer Sam and his family moved to another state, and the couple ended their relationship.

Determined to get Sam back in the glee club, Finn and Rachel tracked him down at his new job at a strip club. Sam returned to McKinley High and discovered that Mercedes was now dating Shane.

Sam vowed to win her back, and the pair eventually kissed. Although Mercedes confessed the kiss to Shane and broke up with him, she did not agree to date Sam again. Sam later recorded Mercedes singing "Disco Inferno" and posted it on YouTube, hoping to show the world how talented she is. When he revealed what he had done, she finally realized how much he still cared for her. They kissed and began dating again.

As the seniors prepared to leave McKinley High, Sam and Mercedes celebrated the recording contract she was offered as a result of Sam's video. He then joined the other students in a musical tribute to their graduating friends.
