Warning: This story contains spoilers for Part 2 of Outer Banks season 4.

The Pogues family is about to expand by a member.

In part 2 of Outer Banks season 4, Madelyn ClineSarah Cameron’s character learns that she is pregnant by her long-term boyfriend-turned-husband, John B’s (Chase Stokes) baby.

The reveal is the first of its kind for the hit Netflix series, which sees the treasure hunt stakes rise with each season but has never introduced this kind of twist before. This also comes after fans speculated that Sarah might be pregnant when the trailer for Part 2 premiered at the Poguelandia fan event in Santa Monica last weekend.

Sarah confirms the pregnancy in episode 7 after slipping into the pharmacy bathroom and taking two pregnancy tests, both of which were positive. When Kiara (Madison Bailey) comes knocking and sees the tests on the sink, Sarah immediately spills the bean.

Joking that it’s “impeccable timing” given their fight to hold on to the land they purchased at the start of Season 4 with El Dorado’s gold and their continued quest for the treasure of Blackbeard, Sarah’s nerves are immediately visible.

Kiara doesn’t really help when she describes their dire situation. “I mean…homeless, broke again, hunted by killers. I don’t really know how it could get better.”

“It would be super awesome if maybe you could find one positive thing?” Sarah asks him, triggering a sweet moment between friends.

“You’re going to be an amazing mom. And John B loves you,” Kiara tells Sarah. “And you have us all. They say it takes a village.”

Sarah doesn’t keep the news to herself for long – despite Kiara’s various attempts to get it out of her – and tells John B in episode 8.

As expected, he is as nice as possible after hearing the news, despite his obvious shock and fear.

“I’m really, really scared. I don’t know what to do,” Sarah told him with glassy eyes. “I don’t know how to do this. I know you don’t know how to do this. And we’re… so young. And I know the timing is probably terrible.”

After John B pulls her over his knee, she admits, “I was really scared to tell you,” but he reassures her, “We’ll figure it out. Because we always do.”

A few days before the premiere of the second part of season 4,Outer Banks was renewed for a fifth season, which its creators said would also be its last.. “My heart is heavy,” Stokes, 32, wrote in a job reacting to the news and calling season 5 “one last ride.”

“Thank you to everyone who has listened over the last five years. You have given us more than we could ever give back,” he added. “It will always be Pogues 4 Life.”
