Is the much-talked about ring on Blair's necklace, as seen in select photos emerging from the NYC set of Gossip Girl this summer, symbolic of the state of Chair's relationship (that they're together but apart, for now)?

We've all seen the Chuck-Blair sex promo by now (if not, you are missing out), so we know the two are on good terms. What's with the ring, though? Is it a harbinger of even better things to come for Chair?

E! Online reports that ... we don't know right now. But we will soon!

Regarding whether it is in fact a wedding band and symbol of Chair's pact, we will "definitely will find out what that's all about in the first episode back." Until then, let the speculation and theories fly in the comments!

On an unrelated note, expect another of B's relationships to play a key role this fall.

Regarding Blair and Serena's oft-strained friendship, the producers really want to bring that back to being "front and center, just like in season one." Now that's something we don't expect a lot of argument about.
