One of the best things about watching TV series (and movies) several years after they were released is spotting current stars in lesser roles before they were famous. This episode features Jodie Comer who was beyong brilliant in Killing Eve. She here, at age 20/21, displays much of that talent, including her ability with accents.
Her appearance comes on top of a great plot and seeing Bacchus take his bad cop routine to the next level. The best thing about Episode 2 of Season 6 was seeing Bacchus regain his mojo in fits and starts after mentally and literally chucking it all in and behaving like a petulant child.
He definitely has his mojo back now but unfortunately much of his sarcasm and bully boy tactics are directed at his wife and a very diligent WPC. However, there is a certain satisfaction in seeing Gently calmly and nicely ask a suspect a question and then Bacchus come over the top with a biting accusation or cynical question and we get a few of those here.
He also is on the receiving end of a stinging remark when a woman, having essentially been described as ugly by Bacchus, retorts with "Yeah, that's rich coming from someone who looks like a horse's head being eaten by a clam." I couldn't stop laughing.
