Revelations

In which Faith gets a new Watcher - who is stuffy, female, tweedy, British, and evil. That's right - female.

Official back-of-box synopsis:

Faith's new Watcher arrives and brings distressing news; she's been sent to report on Giles's performance, and a demon named Lagos is coming to Sunnydale in search of the Glove of Myhnegon. Things get worse when Giles finds out that Angel is back... and that he has the Glove.

From the old WB Buffy website:

TOUGH LOVE - Tempers run hot when the gang learns of Angel's return and Buffy's harboring this vicious killer, but they all must band together to fight a demon who has arrived in Sunnydale in search of a highly powerful weapon. Meanwhile, Faith meets her new watcher, a brisk Englishwoman who is disdainful of Giles' haphazard operations.
