There’s still a year-and-a-half to go until Star Wars: Episode VIII arrives in theaters, which means fans are left with ample time to speculate on what lies ahead in the famed film franchise. Director Rian Johnson provided a fresh hint to obsess over on Thursday when he posted a new set photo on Tumblr. The image doesn’t give away much — it’s just a robe in a cave — but it nonetheless set off a flurry of fan activity.

At this point, principal photography is thought to be nearly complete, according to Cnet. Johnson certainly seemed to indicate as much in his caption, which reads, “in the home stretch.” Although he let the picture do all the talking, fans were more than happy to use words to discuss the significance of the cloak after Johnson also posted it on Twitter.

Many assumed the robe was Luke Skywalker’s, given that he was last seen in The Force Awakens wearing something similar — if not the same exact robe. From there, others made the leap that it spelled bad news for the Jedi. “RIP Luke,” wrote user Dave Donovan.

User Jenny Wilson was similarly concerned for Mark Hamill’s beloved character, urging the director in a hashtag not to be like The Force Awakens director J.J. Abrams.

@rianjohnson @HamillHimself Very mixed feelings about this. If you kill off Luke, I will never speak to you again! #DontBeLikeJJ

Meanwhile, still other fans are convinced that the robe belongs to Rey (Daisy Ridley), and that Luke is either training her and/or is her father.

As much as Star Wars die-hards were happy to discuss their theories, there were also plenty of people who turned it all into a joke, as you might have expected. The photo inspired quips about laundry detergent, what Johnson wears to work, a nude Jedi, and the robe itself being Rey’s father.

Ah, the internet.

Star Wars: Episode VIII is due out on December 15, 2017.
