Good point about Nan being unhappy with the election result.
I disagree with the comment above about Greg being fine. I don’t think Matsson was joking, I think he was hiding the truth behind what sounded like a joke - he wouldn’t take well to knowing that Greg betrayed him to Kendall!
I think what Tom said was pretty close to the truth, that Matsson hates him but Tom had just enough capital to keep Greg employed at Waystar, but at a heavily reduced salary.
From his first moment vomiting out of a costume and getting sacked from a low salaried job in a Waystar amusement park Greg had shown that his only real talent was to parasite on to the Roys. Nepotism had seen him given a title and a salary far beyond what he could possibly have achieved without that family connection.
I think he was still going to benefit from the family connection and through his history with Tom (possibly including Tom’s nagging fear that Greg knew too much), but it would not be as overt. Matsson wanted to run a much tighter ship, cut things to the bone, and and he also found the Roys nepotism distasteful, so I can believe that Tom had to do a bit of convincing to get him to agree to keep Greg on.
