You know, I know we all have thoughts on Hank Summers- If he was actually a good dad, people trying to pinpoint when he stopped caring, etc. but I think a huge point that I haven’t seen anyone talk about was that when Giles came into Buffy’s life he was very involved and cared about her not just as a slayer but as a person, and that was enough to make her realize how uninvolved Hank had been since the move. Obviously this is underscored when Joyce dies and Buffy can’t get a hold of him, but I think the change was in Buffy’s perception of him more than who he actually was as a person. Giles was the one to comfort her after Angel lost his soul and never once blamed her even after Jenny died. He was the one Buffy called when Joyce died because she knew he would show up for her. He was the one she turned to for help. Giles consistently and reliably showed up for her when her father didn’t. It’s not actually about whether Hank is a good or bad father, it’s how her view of him changes as she realizes the kind of care and consideration she deserved all along and her refusal to settle for less.
