When my Buffy and Angel fan edit is viewed in context after the first two fan edits, we see a very clear picture of how Angel has gone from secretly longing for Buffy, to becoming a helpful mysterious stranger who helps point her in the right direction, to becoming one of her most important allies. Buffy and Angel's relationship begins in earnest now as Buffy learns more about Angel and his motivations for helping her, slowly realizing Angel is completely besotted with her.
