This is another entertaining episode. Apart from the nice scenes that were already mentioned, I have to add 2 others that I think worth mentioning: Finch played with Bear in the beginning and he was rubbing his face with his bare hands. No more picking up the tennis ball with protection to avoid germs.
Secondly, when Finch visited Elias in the prison, Elias told the 2 prison guards:* you two can go now" and Finch looked at him in an unbelievable way.
The acting is flawless. Can't wait for another week.
