“Carlos tampers with Gabrielle’s birth control throughout the series! Carlos and Gabrielle Solis had a volatile relationship throughout the show, mostly stemming from how Carlos could never fully ‘control’ his wife. She expressed multiple times her lack of desire for children, mostly for vanity reasons. Nonetheless, it was her decision. Carlos wasn’t having it, so he tampered with her birth control. Naturally, she doesn’t react kindly to the news. It’s seen as a good thing, though, because it’s what he wanted, and they’re married, they’re supposed to have children. In any case, Carlos’ plan sort of backfires: Since she was cheating on him with John, the teenage gardener, the baby was most likely John’s, but we never get to find out since she suffers a miscarriage.
That being said, this was not the end of Carlos’ tampering with birth control. In a later season, he lies to her about having gotten a vasectomy when she had adamantly told him to get one after the birth of their youngest daughter. When she finds out, she is rightfully upset, but Carlos makes her take pity on him by expressing that he lied because he hoped that they would finally be able to have a son. It always felt that Gabrielle was being punished throughout the series because she was the only one of the women of Wisteria Lane who did not want children. Even when she finally has them, she is painted as a bad mother because she seems not to love her children; she could never win in this series, it seems. It was sort of the same case for Lynnette, who kept having children seemingly against her will, because she wanted to keep working, but was discouraged from doing so because of the kids. This series treated women who dared to dream a life outside of motherhood not too kindly.” ― Gabriela Burgos, the co-host of the “Film Posers” podcast
