Sometimes the collateral win and doing the right thing is a personal loss, and while she really couldn't have lived with herself if she'd chosen the other path - well, the U2 song is playing in my head right now, "I can't live with or without you." I think that very much applies with them, and for where I am in the series (here), no much moreso than now.

GUHHHHH. All the Olivia feels... Excellent job here - Olivia with her mask is so spot on, as well as her complicated feelings. Love, LOVED this!
