Once again, being a non-Brit has me at a bit of a disadvantage. I have the entire grid filled in, and I at first had the theme superficially. Coincidentally, in a Peer Review thread a few weeks ago, the activity on which the theme is based was in a video given as a "prize." (First time I'd ever seen it.) Once I found the 8-letter phrase in the grid, and figured which letter to remove, I made the connection. Still, I am not at all familiar with the activity in question, and I am missing one of the removed letters. I have looked up the rules of the activity, but couldn't get there with that. Any suggestions? The V and K reference earlier eludes me.
