Now that "Thor: Ragnarok" is just less than a month away and quite some people have seen the new Marvel film, spoilers seem to be quite inevitable. Chris Hemsworth was recently on an Australian talk show called "The Project" to promote his upcoming superhero flick when the host geared the conversation to some major spoilers in the film. According to Screen Rant, both Hemsworth and Mark Ruffalo were on hand to talk about the film and were both taken aback when the host asked a simple question that would spoil the entire film for fans.

Spoiler warning: Do not read if you don't want to know any potential spoilers for Marvel's "Thor: Ragnarok."

Thor and Hela might be related

In the comic books, Hela is Loki's daughter, making Thor her uncle. But in the upcoming "Thor: Ragnarok," it seems that Hela is closer to Thor than fans may think. In the Australian talk show titled "The Project," the host blatantly mentioned three times that Hela is, in fact, Thor's sister. On the third time, Chris Hemsworth cut off the host, saying, "You can't say it's his sister. You can't give that away." Mark Ruffalo tries to turn the conversation lighter after the tension between the two before Hemsworth asks the host if the show aired live and if they can still rewind the tape.

Unfortunately, the show does air live and has made its way online, spoiling the plot of the upcoming "Thor: Ragnarok" for fans who have seen the video or read stories about Thor's relation to Hela.

Why is Hela angry?

If Hela is indeed Thor's sister in the upcoming "Thor: Ragnarok," it would make sense that she would want to rule Asgard.

Given that she looks older than both Thor and Loki, it would be logical that she would be the next heir to the throne after Odin. Earlier this month, Cate Blanchett spoke to Collider about Hela's motivations, and she explained that the Goddess of Death has been "banished for a very long time and if you were locked under the Asgardian stairs for 5,000 years, you’d be a little bit cross." This begs the question, who banished Hela?

Was her banishment at the hands of Odin himself? Blanchett also hinted that she spoke with Tom Hiddleston to talk about how Loki and Hela "looked very similar," which may be a hint at how Hela is in fact related to both Thor and Loki. Now whether or not Hela is indeed Thor and Loki's elder sister remains to be seen.

"Thor: Ragnarok" opens in theaters on November 3 and stars Chris Hemsworth, Tom Hiddleston, Cate Blanchett, Mark Ruffalo, Tessa Thompson, and Jeff Goldblum. Taika Waititi directs the film.
