This isn't the first time someone in the secret guard being recognized has been a risk, but it's the first time it's taken the story a bit away from the larger war/political plot line.  It could have been a refreshing break and a good way to mix it up, but unfortunately Gregor and Cate were kind of annoying to me personally.  I did expect to dislike the story more than I actually did given the premise, so I guess that's a win?  Still devouring this series though.
