A bit of spoilers...
The final episode was a two-parter, here are the descriptions:
Episode 1: It's been three years since the BBC documentary crew first turned up at the office. Back for one last visit, they find Gareth Keenan now in charge and as the staff of Wernham Hogg know all too well, he runs the office with a military precision. Since we last saw David Brent he has become a sales rep for a cleaning products company, released his own pop single and has acquired a showbiz agent to look after his celebrity appearances. He visits his old place of work regularly, despite him successfully suing Wernham Hogg for unfair dismissal. The big news as far as Tim is concerned is the imminent arrival of Dawn. The documentary crew has kindly offered to fly Dawn and boyfriend Lee from Florida back to Slough for the office Christmas party - an event that may well have a wet T-shirt competition if Keith has anything to do with it.
Episode 2: Tim's world is rocked when Dawn turns up at the office to say hello. Despite a stern warning from Gareth and wise words from Keith in Accounts, Tim can't help but get his hopes up again. Meanwhile, David Brent secured the services of a dating agency and, in between making celebrity appearances in nightclubs for £500 a go, he met up for drinks with a rather disappointing selection of single women. The office Christmas party kicked off like any other but there were a few surprises in store. The first was the arrival of David Brent's date, who turned out to be a very attractive and intelligent woman (almost as intelligent as David). The second involved Dawn, who had left early with boyfriend Lee, but who later returned alone, marching straight into the arms of Tim.
