Plot Questions (ongoing and SPOILERS)
1st episode: Why does the hit-girl have sex with Joe? Is that made obvious in later episodes? Because, it makes no sense in the 1st one.
shareAfter seeing the whole series, here's my theory: I think Frost later on accuses her of being a nymphomaniac. I thought that was just cattiness, but that Joubert saw him as a trophy, as some guys view women. I infer at the end that she actually liked him.
SPOILER for "Three Days of the Condor" film:
Her character reacted to Joe similarly to the male Joubert character in the original film. In that, he admires Condor's resourcefulness, morality and cleverness. He confides in Condor some secrets and warns him of dangers he would face if he stayed in the US. He only went after Condor as part of the original contract. That was canceled, as was the one in this story.
