Oh had no idea it was real lol, but you are saying they are making it like they used each other, not that they are hinting Will is bi-sexual?
and so was Gabi. They both needed some comfort, and I thought maybe it was a last ditch effort for Will to maybe try and "change" his mind. Right after it was over they both knew it was wrong and he left. They talked it out and said it was not a problem and they are both still friends.
