Frank McGrath as Charlie Wooster was only in one scene, standing quietly to watch the trial, and he had no lines at all. This is quite unusual because Charlie is usually quite outspoken, and gives a lot of comic relief to the program. Michael Burns as Barnaby West was in only one scene, and had one line, telling Chris Hale that the people were ready for the trial. This is not so unusual. Since joining the show this season as a regular, there have been episodes in which he doesn't appear, and nothing is said about where he is.
