Pregnancy reveals are unique in the way that they manage to heavily influence a show.
Whether it is a couple getting to explore the next step in their relationship, or a surprise after a one night stand, or even an out of the blue arc that appears because the actress is pregnant in real life, it is safe to say that this plot always leaves room for some shock.
From that reveal comes the discussion about how well it fits into the story currently being told, and that is where many of these pregnancies go down in TV history.
Here is a slideshow of a few pregnancies that stood out when they were introduced on their shows.
Wynonna Earp - Wynonna Earp
There was really no better-kept secret than Wynonna revealing that she was pregnant. This was a plot written around the actress who played Wynonna, but with fans not even knowing that Melanie Scrofano until then, it was a mind-blowing way to set a tone for the second season. The important part of all of this though was the narrative that the show allowed to be explored. With the story choosing not to hide the fact that Melanie Scrofano was pregnant, it opened the door for a strong woman kicking ass while also being pregnant. Wynonna was not any less courageous or valuable and that is the kind of empowerment that the show thrives on.
Amy Dubanowski - Superstore
Amy made it clear earlier on in the show about how she didn't want children with Adam, which set off the events leading up to her leaving him and exploring what being single again meant. She was choosing herself first and then came the pregnancy shocker. It was fascinating in the way that things escalated, especially since this was the point when Jonah and Amy's feelings were finally addressed? The jury is still out on this one.
Caroline Forbes - The Vampire Diaries
It became a pregnancy pattern, with Caroline carrying Alaric's twins as if it was no big deal at all. To this day it isn't always easy to reason it, but it is safe to say that this pregnancy shock up a show known for the supernatural inability to have babies.
Hayley Marshall - The Originals
It is safe to say that absolutely no one saw it coming when Hayley announced she was pregnant. It was a way to bring a newcomer into the Mikaelson inner circle, and yet it was a twist that went against mythology we were told about from the very beginning of The Vampire Diaries.
Heather Davis - Crazy Ex Girlfriend
Having Heather carry a baby for Darryl was out of left field for sure, yet from it came some interesting bonding time between these two characters. It was a decision Heather made in order to help Darryl, which is exactly why this counts as a happy way to have a pregnancy rock a TV show.
Petra Solano - Jane the Virgin
One baby, two babies, three babies, four. Jane the Virgin lulled us into a false sense of security, we all thought the shocking pregnancy of the show would stop at Jane accidentally being artificially inseminated. In true telenovela storytelling form though, it is when you least expect it that something like this happens and changes everything that we knew.
