Catching up with my viewing and commenting after a vacation here, but I didn't see that as romantic either. Sally was incapable of understanding the consequences of sex, at least well enough to insist on the birth control available at the time. And Jacob, although of average range intelligence, may have been sheltered enough to not understand the implications completely either, especially given the lack of long-term or permanent contraception. He would hardly be the first man taken over by hormones, love, and lust, but the potential outcomes were much more disastrous.
This episode reminded me of a long-ago episode of ER, which I may be slightly misremembering, but it featured a high-functioning married couple with Downs who lived independently under the supervision of the woman's sister. They were seen as consenting adults, and that included the right to marry and to not pursue a reliable form of birth control. Not surprisingly, the woman got pregnant and showed up in the ER with her sister when it was time to deliver.
When the baby was born, the sister asked whichever doctor when the authorities would take the baby, and the doctor assured the parents (the couple with Downs) that the doctors wouldn't take a baby from such nice people, in what was supposed to be the tear-jerking triumphant moment of this couple getting to live "normally." But I can't forget the sister being devistated -- pleading that she had to go over to their apartment all the time to make sure that their bills were paid and that they remembered the basic tasks of living, and she was already exhausted from dealing with two families, her sister's and her own. She simply could not take in a baby at this stage of life.
I think that's what Sally and Jacob would have been facing had the baby lived and/or they been allowed to be together -- ultimately, an innocent, live baby would result that someone would have to raise.
