I think we're running into a conflict between what's in character for Veronica (there's a
strip that some have interpreted as potentially being trans* erasure, combined with the original version of 2379), and what's in character for
Jeph, really.
Jeph isn't going to portray Veronica making an insensitive comment about Claire's ability to biologically mother children, even though he likely thinks it's in character for her, because of the effect that it could have on his readers (because he's
been there with 2379, and edited it to remove exactly that). And, I believe Jeph's outright said that Claire's status won't be used for drama.
Nobody's outing Claire even if it would be completely in character for them to do so, because Jeph won't allow them to, I'd guess. It'll be tricky for him to write that in a believable way, but he is a damn good writer, and I'm sure he'll figure it out. Like I guessed earlier, it'll most likely involve Claire coming out before they can out her.
Also... if Claire and Marten wanted a biological kid? I doubt they will, Jeph's had a NO BABIES stance, but it could be done (he's hinted at a relaxation of that stance with
Faye of all people). They'd need a surrogate to carry it, but this technology is being developed in
our world in a couple of different ways (one way which would require an egg donor, then the DNA would effectively be replaced before it would be fertilized; the other way actually involving forcing a type of stem cell to differentiate into an egg instead of sperm, and then that could be fertilized). Then consider that the QC-verse has E-C, and if Claire and Marten wanted it, Hannelore would likely make damn sure they were the first ones to get it.
