I think this episode was the first time I really felt (some) sympathy for Otto Hightower.
I was cracking up during the scene he confronted Aegon and Ser Criston Cole about hanging the rat catchers and sending Erryk to kill Arryk. I thought Rhys Ifans did a convincing job in that scene; watching Otto realize that (1) not only was he surrounded by idiots, but (2) there was no fucking way he could control the idiots was quite satisfying.
Also, Ser Criston Cole just becomes a bigger piece of shit every episode. The audacity he had of trying to blame Erryk for Jaehaerys’ death when he was the one fucking the queen instead of doing him job.
Overall, a really good episode.
