Scrooge, I was about to ask about exactly that, but you beat me to it.

Anyways, another thing I mentioned up-thread was implied appearances. I also discussed this at Thread:272817, and I think it should be added to the table. That is, when a previously known character is implied to have appeared, but isn't implicitly stated. This is usually either due to licencing issues or a stylistic choice. The clues we are given will depend on the media type, and whether or not it is a real-world or in-universe reference. I explained my stances and how it appears this is currently covered with examples in my comment at Thread:272817.
