'The Bullsh*tters'- a quick question

Something small that's driving me nuts- can someone help me out?
In the safehouse when Bonehead and Foyle are lounging around talking about the forensic report of the ransom tape, Bonehead reads out the description of the first voice "black, six foot, mid thirties and gay", Foyle silently mouths something (a name) and Bonehead responds "Nah he's not black"- who does Foyle silently suggest it might be? (the subtitles have nothing for it either)
