R2?

[realms-of-life.livejournal.com]

As usual I'm slow at catching up with fandom talk, so forgive me if I'm asking a silly question.

Does anybody know what "R2" stands for?

Also, does anybody remember a quote (I think it is C.C.'s) in which she asks about the "meaning of a meaningless life" or something like that? I've been trying to remember this one for weeks now. I wonder if I dreamed about it...
