Tom knew it, too. Right after the Tahoe shooting, Michael says, "Tom, you're my brother." Tom practically breaks down weeping: "I always wanted to be regarded as a brother by you, Mike"--which tells me that he didn't think Michael regarded him as a brother.
Did Sonny? He told him That's easy for you to say, Tom, he's not your father
How did you get your hands on this! We'd forgotten this gem
Do we infer Sonny didn't regard Tom as a brother
Poor Tom so wanting to be “regarded as a brotherâ€
Sonny also said
If I had a wartime consiglieri – a Sicilian -- I wouldn't be in this shape! Pop had Genco -- look what I got
Whilst Sonny apologised it showed what was deep inside
Maybe it's something that I've been slow to pick up, but I've recently noticed the parallel between young Vito and Tom, each finding protection under the roof of a family not his own
Thanks Pete for the parallel tidbit between the orphans, young Vito and Tom
What's curious about that scene is that Tom didn't include Fredo in his retort
Poor Fredo didn't get included in anything!
