spoiler for season 8 cliffhanger...
We have some more information regarding the cliffhanger, which was closed off to the audience. We know a few things: 1) For some reason, Ross has an engagement ring in his pocket 2) The ring ends up in the wrong hands 3) Someone proposes to someone (but as Wanda says, it's not who you think) 4) Judy Geller is involved somehow (b/c her name is in the credits, though she does not appear in any part of the eppy that the audience saw, so one could infer that she's involved in the cliffhanger).
My guess (and WISH!!!) Is that Ross finally realizes that he re-loves Rachel, and he proposes. But Wanda said that it's not who we think, so maye this doesn't happen. And I figure that Joey has to play into it somehow! Any other ideas now that we have these details??
