Stranger Things Fans 'Scared For Lucas' After Behind-The-Scenes Leak

Warning: major Stranger Things spoilers ahead

Watch here:

In the exclusive behind-the-scenes video, fans get to see the cast at work, moving from hair and makeup to costume to shooting - and having a hell of a lot of fun inbetween.

However, some fans couldn't help but zone in on one particular moment from the video, when Caleb McLaughlin, who plays Lucas Sinclair, joins Gaten Matarazzo, who plays Dustin Henderson in the makeup trailer.

Fans who have binged the new episodes of Stranger Things immediately spotted a stand-out detail that made them think back to earlier moments in the new season when characters were possessed by the evil Vecna.

When characters like Max, Chrissy, Fred, and most recently Nancy, were taken over by Vecna in earlier episodes, their eyes turned a frightening white colour as they lost consciousness and levitated, moments before meeting their demise - or, in rare cases, managing to escape.

Knowing that Caleb had to alter his appearance for an upcoming scene in the new season immediately had fans concerned that he might be Vecna's next victim.

Taking to Twitter to discuss the potential spoiler, fans of the series admitted that they were worried about what the final few episodes had in store for Lucas.

"See, now ya'll have me scared for Lucas," tweeted one worried fan.

"Why would they spoil that," asked a second.

And a third added: "Right??? Like there's no other reason why Lucas would be wearing contacts?? And the way Gaten reacted to how the contacts looked.... they're definitely the possessed contacts that Max, Nancy and the other Vecna victims had to use."

A fourth fan threatened: "If Lucas dies, I'm not continuing, NOT HIM! NOT MY GOAT!"

Lucas isn't the only beloved character that fans are concerned about, either.

Steve, played by Joe Keery, has been one of the most popular characters since the show debuted back in 2016.

But in more recent episodes, we saw Steve get pulled into the Upside Down and bitten by a bat.

While he seems to have survived the bite for now, some viewers are convinced that this could mean the end for Steve and his fabulous hair.

Stranger Things is available to watch on Netflix now.
