Shit, I wish I still had the email, or we still had comments from the old site. IIRC Gail said it was "placeholder dialog," as in, that's what she put on the page, intending to later get clearance to change it (which she expected she'd be able to), but never got around to it.
It's not a real hard line to work with as is, though, you can easily go the "deep denial" route, since "I AM SO VERY HETERO THAT I AM HETERO RIGHT DOWN TO MY BONES" spins pretty well as "doth protest too much," and the whole running-off-to-Asia-when-Babs-gets-engaged and marry-Ollie-despite-not-having-a-single-real-reason-to shenanigans support the reading of "desperate to assert her heterosexuality."
I love this post, I get to give my favorite icon a workout.
