I tend to listen/watch video clips to help me get their voices in my head again when I'm having trouble writing a chapter. I just hit one that made me grin. See the end of the Bevelle clip (about 3:56) on the Matt McKenzie fansite when the party goes back to save Kimahri. It's tiny tiny, but I love the the brief exchange between the two older Guardians before they go charging after the young'uns. Especially Lulu's almost apologetic smile -- she knows he's right.
