When Buffy first met Willow she could have been described as a sweet, self conscious and often nervous girl. She would exhibit low self esteem and sometimes she’d let people push her around.

Willow plays a very important role in Buffy’s life. She, along with Xander, became the Slayer’s first friends when she arrived at Sunnydale and they have remained her best friends ever since. Also, during the course of their friendship Willow has come a long way from being a modest helper who did some research for Buffy and sometimes quite frankly just a nuisance (Buffy having to help her out of trouble constantly), to becoming a very powerful witch and thus a formidable ally.

In early days Willow would prove useful aiding Giles digging through volumes of ancient lore in search for prophecies, information about demons, stories of vampires and many more useful knowledge that the Slayer could require at any given moment. Also sometimes her computer expertise was used, for instance, for hacking into government databases and such.

Willow’s first contact with witchcraft came out of necessity. Angel had lost his soul and thus became Angelus a vicious murderous vampire so to stop him, Willow created a spell to curse the vampire again with a mortal soul. After that Willow began training in the dark arts and she had a natural talent for that, so soon she became a very powerful witch.
