'Vikings' season 4 episode 11 air date, spoilers: Ivar to kill his brother?

The Irish-Canadian historical drama television series "Vikings" will be back soon for the second half of season 4. It will be kicking off with episode 11 and as revealed by spoilers, Ragnar's son will be killing his own blood.
As detailed in a report, Ivar the Boneless (Alex Høgh Andersen) may possibly kill one of his brothers. Fans may recall that young Ivar previously slaughtered a boy with a hatchet after being bullied during play time. That was his first murder and it indicates that he could be a dangerous man when he is all grown up in part two of the series.
Spoilers suggest that Ivar will take the life out of Sigurd Snake-In-The-Eye brother (David Lindstrom). It's not far from possible because the two shared a painful childhood together under the watch of Aslaug (Alyssa Sutherland). They were always left behind by Aslaug who would meet up with Harbard (Kevin Durand).
As for the reason behind Ivar killing Sigurd, it's said that the latter would continue to envy his younger brother because all of their mother's attention went to him. He hated that fact and always maintained that it was Ivar's fault why Bjorn's (Alexander Ludwig) daughter, Siggy, (Jessalyn Sarah Gilsig) died.
Ivar and Sigurd's bad blood may worsen over time and may lead to a fight between the two. This could trigger Ivar's violent side to come out again and eventually kill off his own brother. If that's the case, it's going to be a bloody season premiere.
Moreover, spoilers also reveal that Ragnar will be returning to Kattegat after several years of being missing. His defeat in Paris against his brother had forced him to run away but he will go back to his land which will be very different now. His sons are all grown up and fit to take over.
Ragnar will also be settling unfinished business with King Ecbert (Linus Roache). Rumor has it that Ragnar could get killed by his longtime enemy in a battle in Wessex.
"Vikings" season 4 episode 11 premieres Wednesday, Nov. 30, at 9 p.m. EDT on the History Channel.
