Afternoon.
Setting up just in case any other binge watchers did want to discuss so the original stays spoiler-free.
Someone asked why Thomas's love letter kept disappearing - I assumed because he was psychologically at peace with it now: does not need to keep rereading source of heartbreak as it was not from his love. But that was a wild guess on my part and not sure why the closure did not allow him to pass on/move on as a ghost like the other one referred to.
My favourite part of the whole series was Pat being lovely to the younger robber, you know, take the better path pep talk...then on seeing him put chewing gum on the table shouting BORSTAL!!!! at the top of his lungs. Cracked me up, probably because of having to try to get all the used gum off school desks with a knife back in the day. You turned a desk upside down and there'd be 30 bits of pink, yellow, white and grey used and discarded gum stuck under each table 
>not envy.
I also thought the Captain's scenes were beautifully done and I did tear up at them.
