You guys are all wrong. We found out last week who the gay guy is.....it's Sawyer! Remember when he was playing "poker" with Jack for the medical supplies? He hinted at needing one of the anti-biotics because he had caught the clap. And where did he catch the clap??? Tallahassee!!! Yep, Sawyer is totally gay for Lockes dad....who may be the original Sawyer. Now that's a plot twist!
