Charlie --->Buffy; Charlie appreciates a good badass "I can take care of my own shit" person like Buffy. She does, in fact. So much so that she considers Buffy family and sort of idolizes her just a bit. She was the first person she spoke to in the City and was so nice to her that it helped Charlie relax some and the lessons she's been taking with Buffy have been quite a lot of fun for her. She wants to one day show her what Aang taught her and hopes that, even if Buffy doesn't have that sort of ability, she can help Charlie figure out how to incorporate her fire into more.
