RDR2: Sonny the Sodomist ... the Bill Williamson Connection (aka BILL WILLIAMSON IS GAY)

It's been debated for a while now as to whether or not Bill Williamson, the butch, ever-so-manly salt-and-pepper chest-hair member of the van der Linde gang is in fact a homosexual (and if he is, that's his business, I'm not making judgments). After Arthur Morgan has had an encounter with Sonny the seemingly in-bred denizen of the swamp immediately north of St. Denis, Williamson will approach Arthur while in camp and admit to having intimate knowledge of both Sonny and what he did to Arthur.
After Sonny's had his fun, we hear a horse whinnying in that video.
