During college, Anya returned to seduce Xander so that she could get him out of her mind. However, she ended up falling
for him and the two have been extremely sexually active ever since. Anya has been accepted as a primary member of the Slayerettes.
Before the final battle with Glory, Xander proposed to her only to be told to give her the ring after, if they survived.
They had to hide their engagement for quite a while due to Buffy's death and then resurection and subsequent adjustments
During the Haloween episode they finally anounced it to the gang and Giles. With the wedding just days away both
of their stress levels were at their highest levels and they were often at eachother's throats particularly since
the visit of one of Anya's old Vengance Demon pals.
Although Anya got in touch with her human side, she stills showed her arrogance and demon-nature by butting into conversations
and biting into Xander (literally). With Giles returning to England Anya officially becomes the top dog, and partner,
at the Magic Box.
