I was scrolling through social media and ran across someone pointing out that Zenos has siblings. I then used the search function and saw this was asked about in a thread to be asked of Oda-san, but I also don't think this ever was asked. So, what does everyone think happened to said siblings? Do we think he killed them? Or that they died during either Varis's fight for the throne or during the fighting after Zenos killed Varis? Of course there is also room that they just forgot about the blurbs about these siblings.

Now I'm personally calling them half siblings due to Zenos's mother dying some time shortly after his birth and that if there were legitimate heirs to the throne you'd think Varis would have chosen the more sane option(s). Unless by that time he had chosen to go along with the whole "Keep Garlemald an agent of Chaos" plan. Which would have meant Zenos would have been the only option.

Do you think they might have died while trying to flee with the rest of the royal family that we learn about in the side quests in Garlemald?
