This was an engaging episode that was interesting, and was interesting for character relationships. Tommy was very interesting in this episode, and Arthur was very endearing and emotionally touching in this episode. John remains the most enjoyable character in the show for me, and I think him and Micheal have the most promise in the show (Apparently, they're played by brothers.) May might be an interesting character, but I don't really know how she would fill into the plot. Sabini is a slimy villain, but the most hateable character for me remains to be Campbell. Alfie is interesting, I would love to see him get more screentime. Polly is such a realistic character, and her finding Micheal is one of the most interesting dynamics of the show. This show is getting very heavy-handed, but a lot of these characters are still quite sympathetic to me. The sets and time period are great to watch here, and it's a great show to look at. The writing is great here, and it's another good episode that focused on character dynamics.
