I don't believe this is preferential treatment or a cover up at all. No one heard him say anything untoward so no case to answer.
So, fuck all happened. There's a suprise. No one else heard anything probably because fuck all was said.
I’m intrigued as to what Gabriel thought he heard.
I’d rather this be the outcome all in all, be a bit weird getting off on a human being calling another human being a racial slur.
