There have been several spoilers made on the "Game of Thrones" season 6 set, and they are pretty major ones.

Winter is Coming has kept close tabs on the IrishThrones, which has been wonderful source of information from Northern Ireland, where the cast and crew of the HBO show have been filming.

They first revealed that major stuff are being filmed in Shane's castle, which has been used both for the High Sparrow's lair and for the Winterfell crypts. The information has been welcomed by fans, but the next ones they will reveal are the ones that are getting much buzz, since it has something to do with the ill-fated Starks.

Apparently, they have gathered substantial evidence that proves Lady Stoneheart will be appearing in the next season.

"**SPOILERS Season 6** CLOSE SOURCES Lady Stoneheart 'WILL' appear and command an army!" they tweeted.

For those who are unfamiliar with her character, Lady Stoneheart is Catelyn Stark come from the dead. She is pretty disfigured and has her throat slit, so she cannot speak clearly, so there would be no need for Michelle Fairley to reprise her role, if ever this spoiler is true. Nobody has seen Fairley near the set as well, so this new character rumor is still up for debate.

Unlike Catelyn, Lady Stoneheart is not a warm, loving mother, and her sole mission is to seek revenge on those who have wronged her family. She will lead an army of outlaws from the Brothers Without Banners.

Lady Stoneheart will be one exciting character to watch, but all the fuss and commotion actually circled more on the next spoiler: "*SPOILERS Season 6* CLOSE SOURCES Jon Snow is the son of Rhaegar and Alyana."

For so long, fans have been theorizing about Jon Snow's true ancestry, which is R+L=J, that this spoiler does not really sound like big news anymore, but the fact that the show will finally acknowledge it is something that has fans clapping and cheering.

Because of this piece of news, more fans have become even more determined to believe that the Lord Commander of the Night's Watch isn't really dead, and will be back next season and for more seasons to come.

When Dan Weiss and David Benioff first approached "Game of Thrones" author George R.R. Martin to do the show, he gave them a test. He told them that he will allow them to pursue the show if the guess Jon Snow's lineage correctly, and they did. The three never breathed a word about the theory, but it looks like they finally let the cat out of the bag.
