I just started re-reading all the comics and I'm up to issue 11. I got some interesting bits of info that might help out.
In The Long Way Home, Part 3, Willow says "I saw the big picture", isn't that also one of the themes of this season, certainly for Buffy? Is this line significant in any way?
In The Long Way Home, Part 4, Willow and Buffy both say that they are a part of each other, which explains how Willow can share her magic with Buffy. What effect does this have on Future Willow?
In Anywhere But Here, Robin says "The important thing is that you rescue the prince." Willow and Buffy both dismiss this comment and it could be something like the cheeseguy from Restless or perhaps it's something that will come up later. Who is the prince? Maybe Harth?
The most important detail is so small you easily overlook it. In fact it's a picture, not words.
In No Future For You, Part 3, Gigi is showing Faith all the surveillance footage of Buffy she bought. Did she track it down herself, or did she let Roden do it? Didn't Twilight say he knows all Buffy's moves? So if you add one and one, I figure Twilight (at least as an organisation) has been monitoring Buffy. Well then, in the frame where Gigi says "No, YOU have much to prepare, Roden." You can see one of the screens in the background pretty clearly. It shows a blonde girl (presumably Buffy) running up some stairs/construction, pushing a hooded man out of the way. Is it just me or does everybody else also recognise this as being from "The Gift". If so, wow, Twilight has been on Buffy for quite a while, if he was already tracking her during Season 5. What does that tell you?
