"This is making the kind of sense that's not."
Since seeing her as an Eskimo, Oz has been enamoured by Willow. He always utter, "Who IS that girl?", every time Willow crosses his path. After revealing himself as a werewolf, he and Willow became closer. He eventually became her boyfriend and secured a place among the Scooby Gang. He is well-known for his short but expressive sentences.
Seth Green is best known for his role as Scott Evil in the Austin Powers movie chain. He and Alyson Hannigan, who played Willow, have known each other for a long time. Before his role as Oz, he played her romantic interest in the movie, My Stepmother Is An Alien. Out of the original Buffy cast members he is the only one who appeared in the Buffy movie. Unfortunately, his part was left on the cutting room floor.
As a tragic truth, a Slayer is doomed to be alone. The world does not know that she exists. She is faceless--meant to blend in. Everyday she puts her life in danger so that the people of the world may live another day. She lives alone and therefore dies alone.
But Buffy Summers lives a different life--one surrounded by friends and family.
Her circle is not by any means big, but in it are reliable friends who have proven themselves time and time again.
Take the time to get to know them as she did...
