I have to say that the episode "Athena Begins" might be one of 9-1-1's best episodes of all time. What made this "Begins" episode different from the others is that Athena was on a mission to catch the killer that killed his fiancé in a robbery, who convinced Athena to join L. A. P. D. The premise was excellent alone, but what it made it better better was the emotional impact you had for Athena throughout her origin story. As of this episode, Athena is my favorite character in the show, with her starring in an episode this good.
