Disney and Lucasfilm are keeping a tight lid on when the trailer for Star Wars: The Last Jedi will drop, but the studios did show off some new footage at CinemaCon yesterday.

The sizzle reel of the Star Wars universe didn’t focus specifically on The Last Jedi, so there were only a few seconds of actual new footage that made the cut. In those few seconds, however, people were treated to glimpses of Rey wielding Luke’s lightsaber and swinging it around, teasing the possibility of Luke mentoring Rey in the ways of the Jedi, according to Comic Book Resources.

It’s impossible to say for certain, though, but director Rian Johnson has spoken previously about the relationship between Luke and Rey. In an interview with USA Today, Johnson said a large part of the movie would be exploring the relationship between the two as they help each other grow.

“But part of what’s she’s dealing with is the realization that she has this power and this gift,” Johnson said. “She’s taking her first step to coming to terms with this thing inside her that she never knew was there and is just starting to reveal its potential.”

Disney hasn’t given a specific date for when fans can expect the first trailer, but Lucasfilm CEO Kathleen Kennedy said the first footage would be shown sometime in the spring. Star Wars Celebration, Lucasfilm’s annual conference dedicated to the franchise, does take place between April 13 and 16, making it the most likely event for the trailer to officially drop.

Star Wars: The Last Jedi will be released on Dec. 15.
