Re: Why wasn't Worf in Code of Honor?
Well, Worf didn't really have a specific permanent station assignment yet at this point in the series. And we know from "Lonely Among Us" that junior officers spent at least some of their time on non-bridge assignments. So I always just figured that Worf was serving a temporary duty assignment in Engineering or someplace during "Code of Honor".
