Aha. I have read C-A-D, so I know of what you speak.
Part of what made the C-A-D situation so gratuitous was the fact that it was so out-of-line with the strip's usual tropes -- heretofore, man-child Ethan could do crazy-stupid things and not be maimed or killed (nor bankrupted by the medical bills). It's more of a pure gaming strip now than it was even then, but there was a sort of "Law & Order" filter; personal lives & issues never intruded on The Story, and now they had. There was a sense, an expectation, that things would -- should -- work out. Maybe many had hopes it would spur him to some personal growth, or just plain grow up. I'm sure there were feelings that the miscarriage was just a cheap "get out of jail free" card. Many artists besides Jeph consider it a lesson learned.
Faye's musings on the matter of having children (courtesy of Sam) does seem to invite speculation on this front. Unless her old problems flare back up, and I don't think they will. She appears to be most of the way to true stability., and in a relationship that seems pretty solid. IF it happened, I'm sure she and Angus would marry, the whole nine yards, and prepare themselves accordingly and responsibly. Either that, end it quickly, while its still little more than a mass of barely-differentiated cells. Either option of course is still controversial for widely different reasons. It's a hard decision that many have to make Real Life. As I'm writing this now, yeah, I can't imagine Jeph deliberately courting controversy when so much of it already finds him. As I wrote my original post, my thoughts were more along the lines of "These Things Happen, Sometimes"
On the one hand, I don't want to belabor the issue; on the other, the point has been broached. And if I'm reading the "conduct" thread right, explaining one's thought processes is safer than just leaving it hang out there.
Even "just" a false-positive scare would be IMO moderately tough for Faye to deal with, but she's the only one who even remotely could; I wouldn't wish it on any of the other female QC characters.
So, yeah, probably Not A Good Idea. At this point, I'm leaving it in my earlier post only to supply context for what followed.
