So the staged sexual taboo conspiracy didn't annoy you?
I was assuming half way through that it would be honestly revealed that pregnant women would be carried into space by their unborn children and who would then both freeze, and then both explode from the effects of the vacuum.
That's a perfectly good reason for a sexual taboo dictating why the two worlds shouldn't cross pollinate.
Or possibly that the halfotherworld babies inside mummy would catch fire in uetero and then explode like landmines while Mom is shopping for prams.
Although if the pregnancy is only going to last a couple hours, before the baby becomes as hot as molten glass, and it sears a route though it's mother skyward, it's possible that the cauterizing effect would make the effect survivable.
However a pregnancy would never get that far... 300 million sperm per millilitre of ejaculant turning white hot, then carving a smeltering freeway spaceforth through mummy's face and shoulders to the VanAllen Belts.
AIDS is ####ing charming by comparison.
