Another outstanding episode. As simple as it was (to get into the bank and retrieve the backup Samaritan), it sure packed a lot of top notch moments and more back story about Finch. I thought it was a great way to bookend his father losing his memory of him and the emotion he had toward Arthur who himself was losing his own memory. Great scene at the end when the 'Machine' gave him a present by playing the best parts of him on video, especially his Wife. Nice twist by having the 'Bank Manager' swapping out the backup with dummies so that Arthur never did destroy it as he (and we the viewers) though. Now it's in the hands of the bad guys. Fantastic writing all around. Loved the torture scene with Root and her ability to turn it on her captor, Control. Can't wait to see what happens next!
