Superb summary of an awesome episode. I'm still pole-axed by that last scene between Reese and Carter. He was sooo crushed by the disappointment and remorse in her eyes. This was in beautiful contrast to to great smiles from both of them as they parted after installing Moretti in the safe house. I also loved how he flirted with her through the baby in that scene at the riverbank.
Reese was devastated by Carter's rejection, which led to the gloom of the scene in which he watched Leila go to her grandparents.
My guess is that Finch makes the move to bring Carter back, perhaps by inviting her to visit the Library at last. In any case, I'm sure the three are back together by the end of the season.
