The cast of MTV's teen drama series, "Teen Wolf" Season 6, has just celebrated the show's 100th episode - and finale. However, eagle-eyed fans have noticed that someone is missing from the party that the production held recently. "The Maze Runner 3: The Death Cure" lead star, Dylan O'Brien, was apparently absent in the celebration.

Most of the cast of "Teen Wolf" Season 6 were reportedly present at the 100th episode celebration party. It includes Tyler Posey, Holland Roden, and Dylan Sprayberry to name a few. But according to Seventeen, O'Brien, who plays as Mieczysław "Stiles" Stilinski on the show, was unfortunately not present in the picture. Because of his absence, some fans couldn't help but wonder if his character would still appear in the second half of the final season.

The fans' worries are all due to the return of O'Brien to the set of "The Maze Runner 3" earlier this month. Dexter Darden shares the picture of the Day 1 film shoot for the third movie on his Instagram earlier in March. This may sound bad, especially to the viewers who are wishing to see Stiles in the second half of "Teen Wolf" Season 6.

There is, unfortunately, no way to confirm if whether or not Stiles will return in "Teen Wolf" Season 6. But series creator, Jeff Davis, teased the fans earlier in 2017 about the character's future in the series. O'Brien has yet to confirmed for return and his character's future "remains to be seen," Entertainment Weekly reported.

Meanwhile, there were speculations doing rounds online earlier this year, suggesting that Crystal Reed may come back. Enstarz previously reported that Reed, who played two characters in the past, might show up in the "Teen Wolf" Season 6 finale. It should be noted that this is just a speculation at the moment, which should be taken with a pinch of salt.
