Jim and Pam share a dance and reminisce a little.  Pure speculation - no real spoilers.  And just a word of warning.  If it were any fluffier, it'd be made of spun sugar. 

There was no way that Pam was in the hallway, crying.  It seemed almost as absurd as Dwight comforting her.  It was just not possible.  Set during “Back From Vacation”

It takes two weeks for everything to fall apart, for something so seemingly well put together (and so poorly thought out) to quietly crumble at Karen’s feet.  (Karen/Toby)  Spoilers through Traveling Salesmen.

Pam spends some time thinking about a recent discovery and trying to figure out just how she's going to handle it.

Speculation for S3 and a whole lotta wishful thinking.  Pam's trying to be gracious about Jim's relationship with Karen - but she's had enough - and tells (shows) him so.
