About Willow and Dawn, here's something from Real Me:

DAWN: (smiling) Willow, hi.
WILLOW: Hey Dawny! (They hug) How's my favorite chess partner? Still leading with your knight?

Dawn shrugs in embarrassment.

DAWN VOICEOVER: Willow's the awesomest person.

Cut back to Dawn in pajamas, now lying on her bed writing in the diary with a smile.
DAWN VOICEOVER: She's the only one I know who likes school as much as me.
