The First Wife is still trying to figure out if she wants to be one. She and her husband have been through a lot the last few years, on both sides. It was before the trouble though when she had an affair with a colleague -- still above the line, but with a smaller spotlight, both compared to First Wife and his own wife who's just as famous too, and should be just as acclaimed. The affair was intense, so intense that First Wife wanted to end her marriage and he was going to end his marriage but then her husband needed her in crisis. So she helped him recover, and as soon as he healed, she fell apart. By the time she got it together, her moment with her lover had passed. He happily reconnected with his own wife (though she has no idea) while First Wife is struggling with what would have been.
As for the Second Wife – everyone’s been speculating about her infidelity recently but they might be focusing on the wrong target. The right target isn’t a billionaire but he’s a pretty successful player too, albeit on a smaller screen. Their involvement led to an award for her, and a divorce for him. She was attracted to him because “he’s the hot geeky type like her husband”. Both insist that they never moved past suggestive texting and heavy flirting and never ended up consummating their attraction. Bullsh-t. There was at least one night and that’s why she’s so freaked out about the takedown that’s been coming to her. She’d be happy if they stayed on the current scene they’re on so long as she doesn’t get busted for this one.
