Pema finds out that she's with child the day Tenzin's mother comes to visit. Katara surprises her with it, using various sneaky questions and methods to determine that Pema is, in fact, pregnant. For several hours after Katara breaks the news, Pema cries from the shock and happiness intermittently, sometimes hugging her mother in law, sometimes turning in the other direction and running when she sees Tenzin so he doesn't think anything's wrong.
When she tells Tenzin, it begins a whole new sensation. He wraps her in his arms, the wind around them picking up, and whispers the first quiet, "Thank you, Pema," in what seems to be a never-ending string of his vocalized joy and gratitude. Whenever he passes her during their daily routines, her husband will sweep her into his embrace, place a hand gently on the barely-there swell of her stomach, and whisper another, "Thank you, Pema."
Finally, the morning sickness begins in earnest, and Pema finds herself skipping meals due to the smells triggering her nausea. Tenzin always manages to find her with two small bowls of plain white rice and they eat their meager dinner together, fondly thinking aloud of vegetable stews and dumplings.
The first time she feels the baby kick against her hand, Pema runs to the meditation pavilion to find Tenzin. Luckily, she finds him walking down the hill to their house on the main level of the island, because she does so hate to interrupt him when he's at peace. He worries until she tells him why she's searching for him so frantically, and Pema places his hand against his stomach. It's the first time she's seen Tenzin cry.
Pema often craves cabbage, and though Tenzin hates it, he will always put up with finding copious amounts of the vegetable in his meals. She feels rather guilty, but eases her mind by thinking of all of the things she'll cook for him without cabbage for the next meal. Sadly, that never happens.
Labor begins in the middle of the night, and Tenzin reacts just how she thought he would- ridiculously. He runs around without an aim for several minutes before she calmly tells him to, "Just go fetch your mother, and bring me a Spirits-damned book for the wait, got it?" Needless to say, Pema isn't the most agreeable person when she's waiting to give birth.
Later, when Pema's holding her baby and Tenzin enters the room only to break down in tears, she feels guilty for screaming at him. When he brushes his fingers across his little girl's face as if he can't believe she's really there, Pema loves him more than ever. And when he suggests a name, it couldn't be more perfect.
"Our Jinora."
