If she had just left it at "explicit violence", she would have been fine. But she specifically says here that there is only one instance of violence in this vid, and I counted at least seven other scenes that contained explicit violence.

Fair point. I meant - and failed to convey - that there was one scene I would consider triggery, and there was also other violence. I've rewritten my post to clarify. My email to the concom to add a warning says "contains violence, particularly against women", which I believe does cover the vid reasonably. That's also why I specified the source, and that no outside source has been used, so vid watchers who knew the fandom would have an idea how much, and graphic, the violence in the vid is likely to be, based on other Merlin vids and/or the source.
