It now appears that he almost certainly doesn't exist in the show; that the "your uncles" line may refer only to Euron Crowseye and Aeron Damphair.
Still, I want to hold off on deleting it until we get the official cast introduction videos for Euron and Aeron in Season 6. I do anticipate deleting this page, I just don't want to hurry.--The Dragon Demands (talk) 09:12, November 5, 2015 (UTC)
We kept the pages for Garlen and Willas Tyrell though, since they were in the family trees issued by HBO, despite their canonicity status. We should try to include all encompassing information on the wiki, yes? You should just do the flag that says this is cut content, and to take it with a grain of salt, as well as adjust this article and other articles to show the canon information. But that's just my two cents, maybe Victarion will appear but it's being kept under the wraps, or will be mentioned in the show. - InGen Nate Kenny (talk) 18:21, November 5, 2015 (UTC)
Actually we might not keep those either, I just didn't get to it yet. Or at least, while Willas and Garlan may or may not exist, the way the Kingsmoot works next season I think there would be no way of later saying "oh and we forgot to mention Victarion". But again, I hold off on this until we get official confirmation...--The Dragon Demands (talk) 19:56, November 13, 2015 (UTC)
