 His next character development and change was after he escaped the Initiative, realized he could not harm any human being because of the chip they put in his brain, and saw his only option as going to Buffy and the Scooby Gang for help.Their relationship then grew slowly from a hostile tolerance to a confusing romantic relationship to a mutual respect and understanding.Spike had setbacks along the way; there were times when he reverted to his former "evil" self and tried to hurt Buffy or the Scoobies.
