This is one that will probably have "episodes" in the same continuity. I love the idea of Beetee and/or AU Wiress connecting with Annie after the rebellion and creating a family together. My headcanon of Wiress is usually pretty maternal and I think she would have wanted to take care of Annie.
Wiress held Tern in her arms and danced around the kitchen. The baby giggled and clapped his hands. Beetee tried not to make any noise. He just wanted to watch them for a little bit without Wiress knowing he was there. He felt the familiar tug at his heart. Wiress would have been such a wonderful mother. In a perfect world, they would have had several children. A world where they weren't victors whose children were sure to be reaped. Now they were safe, but a bit too old. Something of a tragedy, really. Maybe that's why Wiress insisted on moving with Annie to help with her child.
Wiress spun, catching sight of Beetee leaning in the doorway. "Uncle Beetee is awake!" she crooned to Tern. His sweet chubby face lit up. He loved all the adults that took care of him, but perhaps because he was male, Beetee was the particular favorite.
"Bee bee bee," Tern chanted.
"Come here, little guy." Beetee held out his arms. Tern snuggled into his neck for a hug. Such a sweet, loving baby. Wiress pressed her lips against Beetee's cheek.
"Good morning, love." She winked at him as she danced back across the kitchen to check on breakfast. Tern commenced babbling at Beetee, speaking in the baby language that only Tern could understand. A bit like Wiress, sometimes, Beetee thought with a smile. He followed Wiress across the kitchen.
"Annie still asleep?"
"Yes, she was up late with that one." She pointed at Tern with a smile. "Grumpy little Gus." She tickled his belly, making him wiggle and laugh. "Cranky silly babe, keeping mommy up all night." She kissed his forehead, smoothing back his fine baby hair.
Beetee sniffed the air. "Are you making pancakes?"
Wiress turned, beaming. "Yes I am!" She enjoyed cooking, feeding people.
Beetee raised his eyebrows, "You're a miracle worker, Wire. Pancakes while watching Tern." Wiress laughed.
"He helped quite a bit. I don't know how I would have gotten that much flour on the floor without him." Wiress dabbed a bit of flour onto her nose, making Beetee laugh. Soon, the table was full of lovely pancakes, and Tern was strapped into his high chair, trying to get maple syrup in his hair. Wiress let him make a mess; he wasn't doing anything a bath couldn't fix. She did attempt to get him to eat a little bit, though. Beetee was left trying to make sure she ate some.
"You make a beautiful aunt, Wiress." He smiled across the table at her.
"an wi, an wi!" Tern joined in.
Wiress actually blushed a little. Beetee thought it was the sweetest thing he'd seen in a long while. "I love kids, you know that." Beetee took her hand. He knew. Their eyes met for a moment, acknowledging the sad truth. It was only a moment, and then they were back to being happy, being glad to be alive and have a family and each other. "There's pancake batter…" Wiress' words drifted off as she got lost in her own thoughts.
"I'll make fresh ones for Annie when she wakes up." Beetee knew what she wanted to say, he always seemed to know what she meant. She smiled gratefully.
"I'll give Tern his bath." She kissed the top of Beetee's head as she stood, then gave a twin kiss to Tern. "How did you even get syrup on the top of your head?" She laughed as she lifted the baby into her arms. "This will be an ordeal, I can tell."
Beetee watched them walk down the hallway and disappear into the bathroom. He let out a deep sigh of contentment as he gathered the dirty dishes together. Every plan he'd had for his life went away with his reaping. The past forty or so years had been mostly fear and pain and uncertainty. This was truly the first time that he felt free. Wiress' soft singing voice filtered past him, occasionally drowned out by the sound of the water filling the tub. He felt immense peace.
