In the season premiere, "Love Love Love '', Blaine and Kurt agree to be boyfriends again. Blaine still wants to marry Kurt, and stages an elaborate and successful marriage proposal at Dalton Academy where he and Kurt first met, accompanied by New Directions, and all their rival show choir groups, including the Warblers. He auditions for NYADA and is accepted. New Directions comes in second at Nationals, and is disbanded by Sue for not being champions. Blaine graduates as class valedictorian, and then moves to New York to be with Kurt. They start off living together, but though they remain engaged, Blaine ultimately moves out because the two of them realize they still need their own space. The relationship between them goes through rocky patches, including Blaine 's insecurity when Kurt becomes popular at school, and when an influential socialite and NYADA supporter hears Blaine perform and takes an interest in his future career, though she is not impressed by Kurt and ultimately tries to break them up, though she fails and ultimately supports them both. Their engagement is strengthened by having weathered these storms, and Blaine moves back in with Kurt.
