I don't own Warehouse 13 or any of the characters. Takes place sometime in the future, AU after mid-S4. Sort of contradicts a S4 episode (you'll know which one) so let's say it's AU before that, and that never happened.

2009, the stacks of Warehouse 13

H.G. Wells was in the middle of a dreary day doing inventory. She made a point to go as slowly as possible, and examined as many artifacts and their effects along the way, storing away the bits of knowledge in case it ever came in handy. One never knew. This artifact caught her eye because of the first name of its owner.

"Christine Jorgensen's mirror?" she read out loud. Taking a closer look, she saw that it had belonged to the first person to have a medical sex change operation. Holding and looking into the mirror caused someone to experience a sex change of their own. H.G.'s eyes widened and she backed away quickly. She may have envied men their freedoms and rights, but to become one? That was something she had never wished for.

2014, Univille

"Guess what, Izzy is going to have a baby brother!" Christina Wells told her mother excitedly. Isabelle Peters was her best friend in school, and she spent a great deal of time at the Peters' household when there were Warehouse issues occupying the attention of her mother and all of the other occupants of the B&B. Helena was picking her up from just one of those occasions. She had spent Friday night and much of Saturday at their house.

"Oh that is exciting, I must remember to congratulate Mrs. Peters." Helena said. "Put your seatbelt on darling." Christina detested seatbelts but Helena did not take chances.

"Am I ever going to have a baby brother or sister?" She asked, reluctantly snapping her seatbelt.

Helena's eyes widened. She and Myka had been together for over two years now, but they hadn't discussed making their relationship any more official than living in the same room, and they hadn't discussed children.

"I am not sure, Christina."

"Can you still have a baby? Mrs. Peters says you can't if you are too old. Are you too old?"

Helena acted offended. "Darling, I don't think I look NEARLY my age, do you?"

Christina giggled.

"I do not know, actually." She admitted. "I don't know how old my body thinks it is. If we do decide to have another child, Christina, you will be the first to know, I promise."

"But Mummy…" Christina thought of something. "You can't have a baby with Myka, can you? You're both girls. You said that babies are made when a man and a woman love each other and they have sex."

"That is true, darling. If Myka and I decided to have a baby, it would only be one of ours, biologically, but we would still raise it as ours together. Like how Myka is not your mother, but she is part of our family. If one of us were to have a baby, we would both be his or her parents."

Christina thought about that. Helena thought of a better example.

"Your classmate, Grace, do you remember how you told me she was born in China, but her parents adopted her?"

Christina nodded.

"She had a mother and father in China, but they couldn't take care of her, so she got to come here to a new mother and father, yes?" Another nod. "Her parents here did not give birth to her, but they are her parents. They teach her things, they love her, they feed her, they punish her when she is naughty. That is what a parent is, Christina."

"So if you had a baby, it would have two mummys, you and Myka?"

"Yes, darling."

She thought a little while longer.

"Could I have two mummys too? Even though I didn't know Myka until I came here?"

Helena smiled. "I am sure that Myka would be delighted to consider you her daughter."

"I still think you should have a baby so I could have a little brother or sister."

"We'll see, darling, we'll see."

That night, Myka and Helena lay in their room at the B&B.

"Do you want children?" Helena asked abruptly.

Myka craned her head so that she could see her girlfriend's face.

"What brought that on?"

"Mrs. Peters is having another child. Christina asked, and I realized that we have never discussed the matter."

Myka thought for awhile. "I always assumed I would have them. And then I joined the Warehouse, and I assumed that I wouldn't. And now I'm in a serious relationship with a woman."

"Lesbians can have children too, Myka, even in my time."

Myka traced her hand over Helena's stomach.

"I know that…but it wouldn't be…ours, in the same way, you know? It would be mine, or yours, with a sperm donor."

Something was nagging at Helena, but she pushed it aside for now. "As I told my ten-year old this afternoon, parents are who loves you, who cares for you. All this business about DNA, that's not what makes a parent."

"Would you want to have another child?"

"I'm not certain if I could, but perhaps. I would not be opposed to the idea."

"Me neither." Myka said. She grinned wickedly. "I bet Pete would offer his sperm."

Helena stared at her, horrified.

"I was kidding, honey. Kidding."

The inventor relaxed.

"Oh and I meant to mention to you, when we were talking about children having two mothers, Christina asked if you could be her mother too. I assured her you would be honored. I am not sure if she plans to call you something different, but I thought I should tell you."
