The same rules apply here on this board as apply to all the other Complete This Phrase / Fill In The Blank(s) boards. But one that probably shouldn't go without repeating is that the characters in Dark Shadows 2012 live in a universe unto themselves and they are not aware of anything that isn't in their universe, which means for all intents and purposes, while they may be aware of shows like
Scooby Doo, they are not aware of other TV or film versions of DS because, well, that would just be very bizarre.
However, that's not to say that the actors are not aware that other versions of DS exist. So, if you want to somehow reference any other version of DS in your set ups/replies, you must do it through the actors and not through any of their characters.
Thanks,
