Hey, I'm a small JC fan over here, Is just me because I have a weird feeling that Jim's in love with Taraji with the way he talks about her and cries over her leaving and he's very emotional with the scenes that they're in together in the show. Please correct me if I'm wrong, I'm not a troll.
Jim is a devoted husband and father, who's completely in love with his wife. He's committed to his family and would never betray them.As a Catholic he knows that marriage is sacred.
So I don't think Jim is in love with Taraji, I think he loves her. As a very dear friend.Jim was really happy when he had the opportunity to work side by side with Taraji, as he himself has said many times. And Jim must have felt very bad when TPTB got rid of Taraji in that disrespectful way.And he really miss her, especially now when he's the one being disrespected.I think he can feel the emotions of his character, John, who was in love with Joss. John went through the tragedy of having his beloved dying in his arms.Jim is a very sensitive and emotional man, he shows his emotions through his eyes and his voice.
