History's action-adventure drama series, Vikings, is coming back tomorrow with a brand new episode and speculations about the fifteenth episode of season 4 are already appearing online.

The upcoming episode is reportedly offering the fans a heartbreaking scene involving the main characters of the series. It has been speculated that epsiode 15 will be an intriguing episode as Ragnar, played by actor Travis Fimmel, and his son, Ivar the Boneless, portrayed by Alex Hogh, will finally bond with each other.

According to a report from International Business Times, the season will reach a dramatic point as Ragnar Lothbrok, the legendary Viking, will be planning his death. As per the source, the character will reportedly be tortured in a terrible way as he will be brought to King Aelle of Northumbria, played by Ivan Kaye, who does not like him at all from the start.

Some fans are still positive that Ragnar will live through the remaining episodes and seasons of the series. However, his death has apparently already been planned. He was the one who told King Ecbert of Wessex, played by Linus Roache, to bring him over to King Aelle, which was a sign that he wanted the situation to happen all along.

Furthermore, his fourth son with Aslaug, Ivar, will be avenging him for his death, which is the one scene that viewers should look out for. According to Siver Times, official synopsis for the upcoming episode of Vikings includes heartbreaking scenes with the father and son. They will be plotting a battle against the Saxons and they will reach a new level of understanding.

There are also speculations that say Ragnar may surprise King Aelle with something upon their meeting. It is not known yet whether it will be for his benefit or if it will kill the opposing character. This will be something that fans look forward to once the episode airs.

Vikings Season 4 Episode 15 titled "All His Angels" is set to air on December 28, 2016 on History.
