Great reaction...that ending and your reaction LoL......
Remember Tommy has no choice but to do this. Because he F****d over the Odd Fellows etc by killing the priest and stealing the jewels they were going to hang the whole family. Tommy had to make a bigger plan to save them all. He made a deal with the government to save everyone. He had to tell them to be in the one place gor his plan to unfold.
This looks shitty and is, but Tommy doesn't want his family to die.
His speech about them never being accepted into the palaces and upper class is true. He has so much money now and the aeshetics of being rich but he is still a gypsy and that is always how they will be perceived in society.
