This conversational turn is probably best understood as a cautionary tale about mushroom coffee. I change the subject. We talk a little more about the job, about what he wants to do next. Hes not overly concerned about finding some decisive, gestural way to put Jaime behind him, some transformative look-what-else-I-can-do kind of part. For what its worth, if you care to see Coster-Waldau do a totally credible 180, away from all things dragon-adjacent, you can see that happen in 2017s Shot Caller, where hes a white-collar bro who goes to prison after a DUI crash and rises through the ranks of a fearsome white-supremacist gang.
But thats not the point. You are not to think you are anything special. Coster-Waldau has already shot one film since Thrones wrapped, and as soon as hes done here, hell take a car to the airport and fly to Denmark to shoot another one. Hes not working this hard because he wants to put Jaime Lannister behind him. Hes working this hard so that he can take the summer off for the first time in a long time and spend it with his wife and his two daughters, whove grown up alarmingly fast while hes been off fighting for the throne of a fictional kingdom. The work is a thing you do for love. There is nothing unusual about it, as he sees things.
