Tony nominee Jonathan Groff has returned to Glee as bad boy singer Jesse St. James, and the adorable actor swung by Good Day New York on May 17 to talk all about his guest spot on the hit series. Groff revealed that on the upcoming episode Jesse will return to McKinley High School as a coaching assistant to New Directions head Mr. Schuester. While Jesse may have apologized to his ex-flame Rachel (Groff's former Spring Awakening co-star Lea Michele), Groff said he'll be back to his "not so nice" antics fairly soon.
