I honestly think the Randy suit from Tabula Rasa was just them pulling shit from Restless, so I am there with you :p It was the SAME FUCKING SUIT. There is not way they could have planned that for two years. I do think the 'slayers came from demons', Spike's redemption, etc, were planned though
Holy shit at that essay...
While I am constantly impressed by Restless, and just how much of the series is foreshadowed in that episode, I'm also a bit skeptical that some of these things were planned or just put together to resemble what was said after the fact.
For example: The death of Buffy. Joss never had firm plans to end the series on her death AND only wrote the Season 5 finale the way he did because he was in rapidly degrading negotiations with The WB.
Makes me think the "death is your gift" stuff was them circling around and figuring it out later, rather than epic foreshadowing.
Now all of the Dawn stuff with the Faith dream sequences? That shit I believe.
Also, death is your gift was from interventions just a few episodes before the Gift, so I'm sure that was planned.
Edit: should have made this it's own thread since no one's going to see it lol
