Following a conversation with Red about Andy, Tommy came to a horrible revelation.
When Andy threatens to stop helping him with his illegal transactions, Norton tells him that if he were to do this, he would do the hardest time there is, with no protection from any of the guards and being moved out of his one-bunk cell into a cell filled with violent male rapists.
As a result, he was exempt from manual labor and harassment by his fellow inmates, Captain Hadley even beat up the lead sister Bogs following an assault, which left Andy in the infirmary for a month.
He even lobs one at the giant poster hanging on the wall, but to his astonishment, it passes right through.
There is a dedication to Allen Greene.
The Warden didn't want to let Andy get a new trial and leave Shawshank, because Andy was laundering money for him.
