How come you didn't notice?

The Royal family sat in the library enjoying family night together. Charades had become one the family's favourite games – even if Elsa struggled with the simplest words.

Like many times before, boys had teamed up against the girls.

"Okay, Olaf. You're up." Anna handed the snowman the basket so he could pick up his next word. "You've got to act out just one word this time. No rearranging. Got it?"

"Got it!" Olaf picked a new piece of paper and froze for a second. The word written was not difficult, but for some reason he wasn't sure how to act it out. He looked around the room to help himself, and that's when he saw Elsa. Perfect.

Not wasting anymore time, he pointed to Elsa.

"Elsa!" said Kristoff hoping it was that easy. "You," he continued when Olaf pointed to himself. "You and Elsa."

Olaf stood right beside her and continued pointing to the both of them. Thinking fast, he pretended he was shivering and put one of his snowballs foot in Elsa's hand.

"That counts as rearranging, Olaf. Put your foot back to its place," warned Anna.

"Cold. Snow!" tried Kristoff. Not wanting to be distracted by Anna's complaints. "Snow hand. human. Snow human, no, that's not the name. Snowman!"

Nodding his head eagerly, Olaf pointed to himself again and then pretended to be taller, scarier.

"Marshmallow?" Kristoff watched him smile and knew he was getting closer. "Marshmallow, you… Elsa."

Not wanting to waste more time, Olaf held Elsa's hand and pulled until she was standing next to him. He moved Elsa's hand until it was resting on top of his head.

"Oh, oh, creator! Snow creator!"

"Hey, it's not fair if he interacts with Elsa like that," complained Anna noticing Olaf was taking advantage of the situation. "And you," she said calling her sister's attention. "Don't help him!"

"I'm not doing anything!"

Olaf continued playing, not paying attention to the sisters' argument. He knew he didn't have much time. He pulled Elsa's hand once again and forced her to start walking in the room with him, never letting go of her hand. All of a sudden he stopped and hugged her legs.

"Walking with your creator. Taking a stroll with her? Hugging your creator!" Kristoff watched Olaf jump in front of Elsa, with his arms held high. "What are you doing?"

"You want me to pick you up?" asked Elsa. She knew he was still acting, but for some reason she couldn't deny his request and soon she was holding him in her arms.

"Elsa, can you please stop helping the other team?"

"I'm not helping him," she complained. "I don't even know what he wants!" She was not going to ignore Olaf if he needed her.

"Be picked up. Be in her arms!" continued Kristoff knowing he didn't have many seconds left. He looked attentively how Olaf moved from side to side, forcing Elsa to do the same. "Rock a baby. Baby? No. Mother's arms? Mother! Mother!" he repeated with a triumphant laugh. "She's your mother, of course!"

"Yes!" said Olaf and then laughed, happy Kristoff guessed correctly. "You took forever to guess! Even Elsa got it before you this time."

"Olaf…I don't think she was helping you." Anna had guessed the word before Elsa got up from the couch, and for a moment she thought her sister had guessed the word too. But now, seeing her sister frozen in place, still trying to understand what was going on, gave her the idea Elsa hadn't had a clue. And something told Anna she hadn't had a clue she was Olaf's mother either.

Any painter would have given anything for their clients to stay as still as Elsa was at that moment. She held Olaf in her arms, but she was unaware of the snowman's requests to be put back down on the floor.

"I think she's still in shock," Kristoff whispered to Anna.

"You okay there, sis?"

"I'm… a mother?" She muttered. Not paying attention to Anna's question.

"Did you know the big encyclopaedia defines mother as the female who bears some relation to their children? But, it also says that word could be used to talk about a woman in authority or an elderly woman? Funny because Elsa is all of them at the same time!"

"You think I'm your mother?"

"She really must be in shock not to notice Olaf just called her 'elderly woman'," whispered Anna. She now had all the reasons she needed to start calling Elsa a mother.

"Of course you are! You gave me life and a name."

Elsa's astonished expression had been fun, but Anna was getting worried by her sister's lack of reaction. Trying to help Olaf get his point across, she said, "you are always pampering him. You even spent weeks trying to improve his permafrost so he could go and enjoy the sun."

Olaf laughed remembering the tickles the 'freezing sessions' – as Elsa called them – made him feel.

"You even helped him win right now," commented Kristoff. "Wait, if Elsa's his mother, doesn't that make Olaf Prince of Arendelle?"

"Uh? A Prince?"

"Yes, he is!" Anna had never thought about it before, but now she realised it was true – in a weird, complex, way. "A charming little Prince. C'mere!" she said excitedly.

Elsa's eyes widened. "Olaf… Pr- Prince of Arendelle?"

Not paying attention to his creator, Olaf jumped from Elsa's arms and ran towards Anna to give her a warm hug.

"But just to make sure, let me be the next in line to the throne, okay? I'm not sure the house of Aren contemplates snow heirs." Anna played with his nose, making Olaf giggle.

"You okay there, Elsa?" laughed Kristoff. He had never seen her face paler.

"I- I need to sit down for a moment."
