>I have to appreciate though that you went that deep for a slumber party episode of season 1 when lore and implications didn´t carry that much the tone of the show. If you had told me about the premiere, I would have expected it but Look Before You Sleep is a really odd choice that I wouldn´t have imagined to use for a lore viewpoint. Yeah it is, but that line has always stuck with me and it does carry a small but possibly significant implication that I decided I would use. It's an interesting debate in how relevant each season is to each other and I have been trying to come up with a system to judge what counts as "cannon" and what rational theories can be made. I think I have mentioned this before of what my working model is: episode canon, seasonal canon and then show canon. The reason why I say working model is because of all the problems it entails. Say there was something that was implied pretty strongly for the first 7 or 8 seasons only to be contradicted in season 9? If show canon equals the whole does that mean that season 9 trumps everything before? I'd say it is harder than a simple yes or no. I think different seasons had different intents and the problem with making rational theories is that many look at the show with too much of a unitary view of the storyline while it probably be best to break it down into seasons or eras and judge what the writers were planing at the time. Here is my working model in how I view the seasons:
Lore Seasons: Season 4
Season 7
These seasons were the ones that were paying the closest attention to a unified story. Probably where you could give the most consideration to small details and background elements.
