When you factor in that Joe and Dustin are gay and the rest of the men in the house are likely straight, I doubt that gonorrhea will be spread in the house unless someone hacks the BB America's Player tasks and lists "Unprotected threesome with Joe and Dustin" as one of Eric's tasks.As for the whole flim-flam between those two, there is that little bit about he who doth protest too much **coughJoecough** It's entirely possible Joe screwed around, pinned it on Dustin, and trashed the guy all over town just to hide the fact that it was he who cheated.
If Amber or Carol wins POV and Joe goes up and gets evicted, it might give a whole new meaning to the term "backdoored"...
