Killing some time here.
One thing i never bought was that Castellano actually ordered the hit on Gravano's brother in law. I think Gravano did it on his own for a personal reason not really known.
I also think one or 2 other murders were based on out right lies he told Gotti in order to to take over a business/ racket or two. Gravano was a true sociopath.

Gravano's indifference to killing his own brother in law and best friend is astounding.

Cat was cold as ice.

Nicky wrote his own ticket, he was going to get whacked and there was nothing Gravano could do about it. He was messed up on drugs, rumored to be gay, and I think he insulted a ranking mobster or something of that nature. Gravano supposedly didn't take part in the planning or execution of Nicky, he just did nothing to stop it.

Which drugs was he supposedly into? Is he really gay or bi or is that just a rumour?

I think Gravano's book stated he was into cocaine pretty heavy, and Sammy had to get him out of some sort of trouble at a gay night club, the basis of the gay rumor. I have no idea if he was bisexual, that's gay in my book, no offense.

Actually there's a difference as gay men are only sexually and romantically attracted to men, while bisexual men are sexually and/or romantically attracted to both women and men.
