Cosette's flitting around in between songs whenever she doesn't have to once again drag Enjolras aside to re-straighten his tie. (The boy feels the need to expose his upper chest like some 19th century harlot, she swears.) She's welcoming any requests people might have, so just pull her (or Enjolras) aside during one of their breaks to get a quick word in; don't worry, she doesn't bite.

Needless to say, the lark is enjoying being in her element, but she's only glowing figuratively.
