For anybody who's interested, I've written a sequel to this story. My take on how Olivia reacts to Peter's confession. I didn't want to add it to this fic since I would have to bump the rating for the whole thing to M only because of one chapter. Yes, there will be smut along the way. If that's something you'd want to read, it's called 'The Truth' and you can find it under my user name. I tried posting the link here, but won't let me, it always has the beginning snipped off and comes out as:
.net/s/7026083/1/The_Truth
First chapter is up, the rest is (almost) done and will follow over the next few days.
