she'd have a lot of respect for rachel. jo is the daughter of a singer (think linda ronstadt) and a music manager who never married and split up when jo was really young. she grew up with her father mostly and a ton of half-siblings. she wanted to get into music at first but realized she was never going to be as good as her mother so her dad got her involved in acting classes. when she was on buffy she felt the pressure of needing to do well and she would go off on her own sometimes and just ignore her costars because she felt the pressure to keep the show going. toward the end of the show that ceased but she always wanted to do well. she cares about people liking her quite a bit and some think that she comes off as fake because of it.
