Efron isn't the only East High alum to return.

In a May interview with E! News, Efron said that he was open to that idea.

"My heart is still there. That would be incredible. I hope it happens," he said.

Whether or not Hudgens and Efron make a comeback, Hudgens had passed along a symbolic torch to Olivia Rodrigowhen she interviewed the singer at the Met Gala.

Rodrigo plays Gabriella in High School Musical: The Musical: The Series and says that they were "soul sisters."
