Many fans of "Game of Thrones" are still holding out hope that Jon Snow (Kit Harrington), the beloved Lord Commander of the Night's Watch who met a mutinous, untimely end in the Season 5 finale, will somehow return to life in the HBO fantasy series' future. However, Maisie Williams, who plays Arya Stark, a character whose become a bit of an expert on death these days, does not share that optimism.

Speaking to E! Online, Williams revealed that she believes Jon Snow is gone for good.

"I think people are trying to be very positive about this, like, ‘It's fine. He's coming back. He's totally coming back, right? He's going to come back?'" says Williams. "I'm like, ‘I don't think so. I'm very sorry!' We saw him get stabbed like five times in the chest. I think he's gone. I mean, I could be wrong, but I really don't think so. And people are like, ‘He's going to come back as White Walker!' I'm like, 'Really, we'd bring back Jon Snow as a White Walker?!' OK, you can believe what you'd like."

Williams even addressed speculation that Melisandre's (Carice Van Houten) arrival at Castle Black just before Snow's tragic end means that the "Red Woman" will use her special Lord of Light magic to revive Snow, whom she seemed to take a liking to over the course of the season.

"I feel like she's far too selfish for all of that," says Williams.

Well, that sure puts a damper on fans' hopes. However, it is important to remember that Williams is about as in the dark on Jon Snow's fate as any viewer. In fact, not even book readers have a clue about what will happen. George R.R. Martin's published novels in the "Song of Ice and Fire" series also left Snow's fate as a cliffhanger.

Plus, Emilia Clarke, who plays Daenerys "Mother of Dragons" Targaryen on the show, contradicted Williams in an interview last week with MTV News.

"I mean, if I had to bet, I'd say there's a 50/50 chance. I mean, there's some helpful people there who could bring him back to life," Clarke said of Snow's fate.

Then again, Harrington told fans, "I'm dead. I'm not coming back next season."

Who should fans believe? Well, they might just have to wait for Season 6 and find out for themselves. "Game of Thrones" will return to HBO in spring 2016.
