Hit TV series "Teen Wolf" has premiered its sixth and final season, and fans are getting worried over Stiles (Dylan O'Brien). However, actor Tyler Posey (who portrays Scott McCall ) continues to assure fans that Stiles will be okay for the rest of the season.

"Teen Wolf" is currently airing its final season, and fans are clinging to every episode that the show has left. "Teen Wolf" tells the story of Scott McCall, a normal high school student in Beacon Hills. Scott was living a normal life until he got bitten by a werewolf, and eventually became one himself.

For "Teen Wolf" season 6, it has been hinted that Stiles might become a mere memory. What's worse is that he might become a forgotten one. In the premiere episode of "Teen Wolf" season 6, fans were shown how the parents of a boy named Alex were taken by ghost riders from the Wild Hunt.

The Wild Hunt occurs when evil entities take the souls of the living, and erases them from the memory of others.

In an attempt to save Alex's parents, Scott and Stiles followed the boy into an abandoned house, where they eventually found themselves under attack. Turns out one ghost rider is present in the house, and has showered them with a bunch of magic bullets.

As an effect, Stiles recognized little by little what was happening to him. First he was getting emotional about his upcoming graduation. Next, he struggled finishing the forms for the school picture taking. And lastly, he forgot about his lacrosse practice and even saw his jersey being given away. Only then did he realize that he was being erased from memory. After confirming this, Stiles immediately tells Lydia (Holland Roden) to not forget him.

The premiere episode of "Teen Wolf" has gotten fans seriously worried about Stiles, but according to Tyler Posey, there's no need to worry at all.

"It's gonna be OK, babies. It's gonna be OK. I know how much you guys are connected with Dylan, and I know how much you love him, but Dylan is one of my best friends. So I miss him quite terribly sometimes, but I'm letting you know I make it through it OK. So if I'm gonna be OK, you are gonna be OK. I promise. I promise," Posey said.
