After verbally sparring with Lars, Elsa was tense and needed to calm down. She went to her throne to sit down and sip her hot chocolate. She wanted to put Lars out of her mind, but she had trouble thinking about anything else, and while every swallow of the warm sweet drink made her feel more relaxed, it wasn't helping to distract her mind. She still couldn't keep her mind focused on anything but the enigmatic Weseltonian. She didn't even notice as Olaf wandered into the ballroom and came up alongside her throne.
"Hi, Elsa," Olaf said.
"Oh. Hi, Olaf," Elsa replied. She took a sip of her hot chocolate.
"What's that?" Olaf asked, pointing at the teacup.
"Hot chocolate," Elsa said, and took another sip.
"Ooh, can I have some?" Olaf asked.
"Don't you remember what happened last time?" Elsa replied.
"Oh, yeah," Olaf giggled. "That was embarrassing."
"It wasn't just embarrassing, Olaf," Elsa said. "If I hadn't been right there, you might have completely melted. You have to be more careful."
"Is that why I can't go with Anna and Kristoff on their trip?" Olaf asked.
"Well..." Elsa considered for a second. "It's not the only reason, but it is a good one," she answered.
"Because I can be careful," Olaf said excitedly. "I really can. If I promise to be really, really careful, then can I go?"
"Olaf, this trip is just for Anna and Kristoff," Elsa said. "I'm not going with them either."
"Then how come Sven gets to go?" Olaf asked.
"Sven has to pull the sled," Elsa replied.
"But I want to see Kristoff's family," Olaf whined.
"I know you like the trolls," Elsa said, "but you can see them some other time, okay?"
"Yeah, I guess," Olaf said dejectedly.
"Queen Elsa!" a voice called out from across the ballroom. The voice came from Prince Lloyd, but all five of the foreign princes had spotted her and were practically climbing over each another to be the first to get to her.
"Oh, no," Elsa whispered wearily, slowly shaking her head. She wasn't ready to deal with them again yet.
"Well, I'm gonna go mingle," Olaf said, oblivious to Elsa's distress. His mood had suddenly brightened for no reason at all.
Olaf abandoned Elsa to the princes and ventured out into the sea of wedding guests. Most of them had never even imagined a living snowman before, and for a while Olaf enjoyed all of the attention. Everyone he met gasped in amazement and laughed at his jokes. Eventually the novelty wore off, though, and as the evening wore on, the guests had their fill of amusement and returned to their dancing and conversation.
Olaf grew bored with the ball and wandered outside into the torchlit courtyard. It was getting late and the crowd of Arendelle citizens had dissipated, though many still lingered in hopes of catching another glimpse of the newlyweds. Olaf was not an unfamiliar sight to the people of Arendelle. He spent a lot of time out in the town square. He saw many familiar faces in the courtyard. People waved to him, but because they saw him all the time, they weren't overly excited about seeing him now.
Olaf found himself at the stables and went inside to see Sven. Kristoff's sled was also there. It had been fitted with wheels and decorated with flowers for the wedding. It was already packed for Anna and Kristoff's honeymoon trip.
"Hi, Sven!" Olaf said to the reindeer.
Without Kristoff there to give him a voice, the only response Sven could offer was an excited snort.
"You sure are lucky, Sven," Olaf continued. "You get to go with Anna and Kristoff to see the trolls. I wish I could go with you."
Sven leaned out over the gate of his stall in an attempt to eat the carrot that was Olaf's nose. Olaf seemingly ignored him and wandered around the stables.
"Besides, how much fun can they really have without me there?" Olaf went on. "I'm lots of fun."
Olaf climbed into the back of Kristoff's sled and starting rooting around in the bags.
"I bet if I were there with them, we'd all be a lot happier," Olaf mused. "I could go by myself and meet them there, but I don't know how to get there."
Olaf produced an extra carrot from one of the bags in the sled. He hopped down from the sled and offered the carrot to Sven, who eagerly clamped onto it with his teeth and chomped it down.
"If only there were some way to go with them without them knowing I was going with them until we got there," Olaf said, leading absent-mindedly against Kristoff's sled. He watched the reindeer finish off the carrot before he eventually came to a sudden realization.
"That's it, Sven!" Olaf exclaimed. "I'll just hide in the back of the sled. Anna and Kristoff won't even know I'm here. Then when we get there, I'll jump out and surprise them. They'll be so excited to see me, and we'll all be happy."
Sven snorted disapprovingly.
"Oh, Sven, it's a great idea," Olaf said.
Olaf climbed back into Kristoff's sled. He searched through the luggage and discovered a blanket.
"Look, I'll just cover myself up with this blanket," Olaf said. "They'll never see me. It's perfect!"
Olaf tossed the blanket up in the air and let it come down on top of him, then he rolled himself up in it. He settled down among the luggage in the back of the sled. Then he suddenly had a thought. He popped out of under the blanket and looked over the edge of the sled at Sven.
"Now, Sven," Olaf said. "You have to promise not to tell anyone I'm here."
The reindeer silently stared back at the snowman with a quizzical look.
"Promise?" Olaf asked, pointing a stick arm at the reindeer.
Sven gave Olaf a reluctant snort.
"Okay," Olaf said cheerfully. "Good night, Sven. See you tomorrow."
Olaf disappeared back underneath the blanket. He wrapped the blanket up around him and curled up in a corner in the back of the sled.
"This is gonna be great," Olaf whispered to himself. "This is the best idea I've ever had."
And with that thought in his head, Olaf drifted off to sleep with a satisfied smile on his face.
