Most of the boxes should be obvious. However, from prior experience with Season 7, the few words that fit into a box are not enough to make it clear what counts and what doesn't. To prevent arguments between friends, we're laying out the rules in detail, in advance, wherever they are not trivially simple.
Some general rules:
- Episode openings and credits don't count, ever.
- Unless stated otherwise, the item, character, object or location mentioned in the box must appear on screen. Flashbacks, imaginary sequences and in-world media, like portraits, also count, but simply being mentioned in speech or writing does not.
