Following the premiere of Game of Thrones Season 8 Episode 3, fans immediately began theorizing where the story was headed next. The HBO show has viewers scrambling for clues on what we can expect when Episode 4 arrives this Sunday, and now a new theory suggests that we've not seen the last of a certain army just yet.

Despite Arya Stark defeating the Night King in a heroic move, some fans are convinced that the Night King still might be alive. Fans should know by now that the show is capable of surprising viewers quite frequently, and with everything the cast has been saying about the final three episodes, there's reason to believe there could be more White Walkers yet.

One Reddit user, as highlighted by BuzzFeed, pointed out that the Season 8 teaser trailer showcased Winterfell overtaken by the harsh weather, and they claim that this could imply the Night King could still reign victorious. While it is a good point, teaser trailers can feature red herrings. However, another theory goes even deeper, highlighting the importance of Little Sam, who was originally supposed to be sacrificed to the White Walkers back in Season 2 as their 100th baby.

"I found myself realising that perhaps Little Sam has a bigger part in this whole story than I realised," Reddit user TurntCrawdad wrote. "When I was reading about Gilly [Little Sam's mother], I came to understand that her name originates from the real-life plant known as gilliflower/gillyflower. Gilliflower is mentioned in Shakespeare's A Winter's Tale, in which they are 'cross-fertilized by humans, rather than by Nature: I have heard it said/There is an art which in their piedness shares/With great creating Nature... I'll not put/The dibble in earth to set one slip of them.'"

Basing their theory around this, they believe that Gilly and Little Sam may have White Walker DNA. "Gilly's name and the mention of gilliflower in a Shakespearean story certainly can't be a mere coincidence," they continued. In Season 4 Episode 4, viewers were given a tease of White Walker babies, but they never popped up again. Regardless of whether Little Sam does, in fact, have White Walker blood, there's still (maybe) 99 White Walker babies in the world of Westeros.

To add even more fuel to the theory of White Walkers making a return, David Benioff and D.B. Weiss, the showrunners for Game of Thrones, recently appeared on Jimmy Kimmel Live to talk about the show. When asked by Kimmel if we were going to see White Walkers again, Benioff responded, "Yeah, we're not gonna answer that."

Meanwhile, the official Game of Thrones Twitter account tweeted in High Valyrian on Friday morning.

The translation? "All men must die." Episode 4 airs this Sunday (May 5).
