Far as I can recall, outside of the bandleader story (which she whined and coerced out of him) ... all he did was fill her in on how Tom is his brother without the same last name, what a consiglieri is, and agree that Luca Brasi was a 'very scary guy'.
I don't see how explaining how Johnny got released from that contract is even remotely considered breaking of 'Omerta', since the bandleader's brains did not end up on the release.
A wise and frugal government, which shall leave men free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned - this is the sum of good government.
