 His role at TNT&G frequently centers on predicting the moves of the prosecution (or the opposing party in civil suits).In "Prior Convictions" he is forced to defend a man he had previously convicted; over the course of the episode he learns that the man, Joshua Morton, had been convicted more because of his lawyer's incompetence and the jury's prejudice than anything Graves had done, and later is presented with proof that Joshua could not have committed the crime.He is fluent in Spanish, as seen in the show's last episode.
