Elliot and Olivia been partners for three years now and Elliot had got cheated on by Kathy, so he was free to get with Olivia now.
They are a really cute couple. Nothing mean, just a kid!! :-)
They had had each others backs for years, and when Elliot needed more than just someone to make sure he didn't get shot, Olivia was once again there for him. However, this time it was for a much more difficult and complex reason, one that would change their relationship forever.
