It’s been 42 years since the iconic movie Grease first came out, but it is still beloved by audiences everywhere to this day.

Spoiler Alert: As we all know, the movie ends with the characters Danny Zuko and Sandy Olsson, played by John Travolta and Olivia Newton John, riding off into the sunset together. Since then, fans have speculated about what their fate was, and all kinds of theories have been put out there. According to Travolta himself, however, Danny and Sandy really did have a happy ending.

A few years ago, a theory went viral that Sandy had actually drowned during summer vacation, and that she imagined all of the events of the rest of the movie while she was in a coma. Evidence supporting this theory included Danny’s “Summer Nights” lyric, “I saved her life; she nearly drowned,” and the way the movie ends with them both driving off into the sky.

When asked about this theory by USA Today, Travolta said, “I love it; imaginations are awesome. These things are bound to happen to something timeless like this. It’s so fun.”

However, Travolta went on to push back on the idea.

“I could have fun with it,” he said. “But I know the writers of Grease, and I was around in the original days. I can’t take it too far.”

Travolta then said that he believes Danny and Sandy went on to start a family.

“I think they had several kids, which people did in those days, they adored their kids, and they held onto their romance,” he said. “Sandy and Danny were the real deal.”

As for the lyric about Danny saving Sandy, Travolta thinks he was just exaggerating.

“He’s bragging; it was made up to impress the boys,” he said. “(Sandy and Danny) have two different stories and somebody is lying. Most likely, it’s Danny. But I don’t want to spoil the fun for everyone.”

Though Grease director Randal Kleiser has stayed silent on this fan theory, he has promised to answer at length in an upcoming book he’s planning. However, he has previously dismissed Sandy’s flight to heaven “as the reason for the ending.”
