The scene in ‘The Gift’ where Tara hits Willow always kills me and makes me hate Glory with an undying passion. I think it’s pretty obvious that Tara was abused when she was younger and every other instance where she’s been around volatile or violent people, she seems pretty terrified. So when she hits Willow, it’s like Glory has truly killed something in Tara. She’s turned Tara into someone she never ever wanted to be; a person who hurts others. That look on Tara’s face afterwords, where she has just a moment of being lucid to what she’s just done, says it all.
