During Thursday's Stevie Wonder tribute (fittingly titled "Wonder-ful"), Mercedes (Amber Riley) and Mike (Harry Shum Jr.) return to encourage the younger Puckerman (Jacob Artist) to take a more active role in the New Directions and become a vocal leader of the club.

"Amber comes back and fills us in on what Mercedes has been up to as she and Harry help New Directions gear up and get ready for regionals," Chord Overstreet, whose Sam Evans has been a de facto leader of the club, recently told THR. "Harry's working on everyone's dancing, and Mercedes is fine-tuning the girls."

While Jake has been quick to make waves with the ladies (Kitty, Marley), he's never really stepped into the vocal role his half-brother, Puck (Mark Salling), previously had with the club.
