Yes, that is the one. Sara shows up and "catches" Jack and Daniel or at least sees Daniel. After her dad dies, she has a talk w/Jack. They discuss or at least she does making a new start. By this point Jack knows he loves Daniel and gently tells her no. She asks about work and he tells her nothing has changed until she asks about Daniel at which point Jack lets her know he would give his job up for him. Sara gets upset and wants to know if there were any other men during their marriage.
