Arc 4: When the Wedding Bells Thaw

Chapter 11- Dressing for the Party.

Everyone; Pen, Marshall, Bartram and NEPTR; were walking towards the castle of the Ice King like they agreed. Pen and Marshall were walking while NEPTR rode on Bartram. Everyone was chatting about nonsense except for Marshall, who was thinking about what happened at the farm after Ice Prince left.

/

After explaining the whole situation to her husband, Mrs. Mertens had a private talk with him after everyone else prepared for the party and tomorrow's wedding. "Marshall, I want you to take care of everyone. That means not getting into too much trouble." She couldn't ask them to not get in ANY trouble, since she knew her son and friends very well. Trouble always came to them everywhere they go, add the infamous ruler of the Ice Kingdom and a 500-year old teenage demon and you have the perfect recipe for utter chaos.

"I know, I know. Don't worry about us Mrs. M" said Marshall with a little hint of annoyance. He wasn't a kid, heck he was ten times older than her. Mrs. Mertens took his right hand into both her hands and looked him directly in the eyes. "Marshall. Promise me please!" The way she said it and the look on her eyes made him stop for a second. She really wanted reassurance that her family would be ok, and that she put her whole trust on him. It almost reminded him of …

"I promise" – answered in a very serious tone. "That includes the Ice Prince. You must make sure that the wedding goes without trouble." That request intrigued the teen. Why would Mrs. Mertens wanted the wedding to succeed. There was something going on that he didn't know but he decided to ignore it for now.

Marshall raised his right arm and looked at Mrs. Mertens in the eyes. "I swear on my word as a demon that I will protect everyone, we will be on time and that tomorrow's wedding will be successful" – His tone was sincere and serious. And she took his word for it.

"Thank you." Mrs. Mertens was now more relaxed; she could trust Marshall to keep his word. "Also make sure everyone dresses formal. It is a wedding after all!" Now her tone was more playful and cheerful. "Yes, I promise that too." Unknowingly to Mrs. Mertens, strange marking appeared on the back of Marshall's right hand.

Marshall looked at the diamond shaped mark on his back hand. How foolish he was for making a promise of such magnitude. He didn't want to think about what would happen to him if he screwed up.

Marshall shook his head to get rid of such thoughts. There was nothing to worry about. He was Marshall Lee Abadeer, Demon Prince. He could keep his promise, and everything would be fine after tomorrow's wedding.

"Finally! We're here!" exclaimed Pen, bringing Marshall back from his thoughts. They stood in the main entrance, admiring the giant doors to access the castle (They could try the window that went into the living room, but they decided it was rude). They stood there for a minute until the massive door opened and were received by Gunter and Jake.

"Woof, woof!/Wenk wenk!" both pets/servants ´said´ at the same time, then they turn around and walked away. "Uh..I think they want us to follow them" – guessed Pen.

After following them from the entrance through a long corridor, they entered the grand hall where the ceremony would take place. They saw a lot of Penguins and snow/ice creatures decorating everywhere, setting seats for the guests, arranging flowers, and a plethora of other things. What got their attention most was a snow structure with stairs in the middle of the Hall that would be the stage for the couple and their bridesmaids and groomsmen.

"Ha! You're finally here!" greeted happily the soon to be husband. "How do you like it, huh. Impressive, isn't it?" They Mertens "party" just nodded on agreement. It looked really good. "Bigger Brother! Where is the bride?" asked a curious NEPTR. He wanted to meet his future bigger sister in law. "My dear Rini, went out! After hearing about you guys wanting to party, she wanted her own bachelorette party. So she and the lady penguins went out to celebrate too." NEPTR just looked down disappointed. "Oh, okay."

"Now that the preparations are almost complete, we can go party right now!"- He was getting exited. He had never had the opportunity to party with people who wanted to be with him. "Wait, wait, wait" interrupted Marshall. "You can possibly expect to go out dressed like that" the grey teen pointed to the Ice Prince clothes. "What about them? I don't see anything wrong with them"

"Dude, take a good look at yourself" – The prince did what Marshall said. He had his holey royal blue cape with his dirty light blue shirt, tattered blue pants, and bare feet. He was in his royal garb. The prince just looked at Marshall with a confused look. "Man, tell me you don't plan to wear that for the wedding."

"Of course not! Gunter picked something special for the occasion"- Marshall sighed. That was good news. He took a quick glace to the mark on his hand; he made a promise to do whatever it takes for a successful wedding, and he couldn't let the groom ruin it by wearing such clothes.

"You better change clothes if you want us to hang out with you!" He was serious about it, if the ladies looked at him hanging with the prince and his crude clothes, he might not be able to score.

"I think I have some other clothes in the closet in my bedroom!" The prince thought out loud, he really wanted to party and if a change of clothes was what was needed, so be it. "Great! Lead the way. Pen! You come too!" -

"What?"

"As for you, Bartram and NEPTR, you don't wear clothes. So wait around for us here!" – Taking charge of the situation and acting like a leader was a very odd experience to him, and a very odd sight for the others to behold. But they just followed his instructions.

"Gunter, keep our guests entertained while I go change. Bring them refreshments and everything they'd like!" ordered the Prince to his loyal commander. Gunter saluted and called other penguins to carry out the orders. "Wenk, wenk, wenk!"

"Ok now follow me to my room!" – As they walked Pen just looked at Marshall. What was up with him. Meanwhile Marshall was trying to relax and not stare at the mark on his hand.

After walking for a minute or two, the trio entered the prince's room and stop in front of a wooden door. "Here it is my closet! But I'm still wondering why I have to change clothes" – Marshall sighed annoyed. He wasn't going to stop asking, was he? "First of all, those clothes are ragged, tattered, full of holes, etc. And second, if you go out like that, people might recognize you, and you don't have the best reputation out there. So if you want us to hang out for your party, you should put on different clothes."

"So, like a disguise? Yes, I think I can do that" The prince opened the closet and turn on the lights, revealing a large room filled with all kinds of clothes; large, short, classy, trashy, gaudy, formal, etc. He had everything. Both Pen and Marshall were amazed by all of these. How the heck did the Prince get all of these? And why he never wore any of it? "If you'll excuse me!" He entered and closed the door behind him, leaving Pen and Marshall alone.

Pen took this chance and turn to Marshall. "Just what is going on with you today? You're acting all weird!" Marshall just sighed again. He suspected he was going to do that a whole lot more until the wedding was over. "I'm sorry, Pen. " It was obvious to anyone that he was acting weird. "It just that.. I made a promise to your mother." Pen raised an eyebrow. "What kind of promise?" the grey teen just took a deep breath. It was kind of a long explanation.

"I promised that I have to take care of everyone and make sure tomorrow's weeding happens. Ice Prince included. But the problem is that I swore on my demon word, and this appeared on my hand!" He showed to Pen the diamond shaped mark on the back of his right hand. "And if I were to fail to keep my word, something really bad will happen!"

Pen was unfazed by the explanation. "So it's like a Royal Promise, right?"

"A what?"

"A Royal Promise. I once made one to not tell anyone about a certain incident in the Candy Kingdom, and after I broke it by accident, I was supposed to die but I had the opportunity to save myself if I answered correctly a math question." Said Pen, remembering fondly that day. Zombies, slumber parties, and the reversal of death itself, a good Tuesday overall.

"Ooookay…..yes something like that, only worse!" He should know by now that Ooo was full of bizarre things, he shouldn't be surprised anymore. Pen smiled at him and gave him a thumps up and the best good guy look he could. "Don't worry Marshall! I'll help you out! We just need to take care of ourselves and the Ice Prince and make sure the wedding goes on without trouble!"

Marshall smile too. He felt relieved to have Pen on his side. "Yeah, dude. With you by my side I can relax and party without worries! High five! Up top!" after their little moment, the closet open once again revealing the newly dressed Ice Prince.

"How about this? Do I look good?" asked the Prince. The two friends widen their eyes at the sight. Gone was the crude and dirty clothed prince. In front of them was a blue man dressed in dark blue dress shirt with the neck unbuttoned, black pants with a classy belt with golden buckle, and finally some black dress shoes. On top of his head was still his golden crown, but his hair wasn't unruly anymore, he combed his long white hair into a stylish ponytail.

"Nice!" complimented Marshall while Pen still held his unbelieving face."But about that crown.." Marshall made the mistake of trying to touch it, because Ice Prince flipped in less than a second.

"NOBODY TOUCHES THE CROWN!" – He had a look of uncontrolled rage as he back stepped with both hands holding the crown on his head. He looked like he was about to attack any second. Pen acting instantly by pure instinct, went for his sword strapped on his backpack. He too was ready to battle the moment Ice Prince attacked.

"WOW! WOW! Chillax, dude!" – Marshall stepped between the two of them trying to avoid a disastrous situation. "I.P. I'm sorry for trying to touch your crown. I didn't mean to make you angry or anything. We are here for you, remember?" He held his hands in front of him as a sign of peace.

The angered prince stood still for a couple of minutes breathing heavily trying to calm himself. For Marshall was the two longest minutes of his life. If the situation went out of control, he was certainly screwed.

"F..fine…. I'm… sorry too. I just don't like other people touching it" The blue man relaxed his stance and so did Pen. Marshall just sighed. Crisis adverted. For now.

"What I was trying to say was that…if you could….not wear the crown on your head! People might recognize you despite the new look." The Prince just gave him with a very serious look. "I will not leave my crown behind! It shall remain with me at all times!" He didn't look like he could be convinced otherwise.

"How about wearing the crown someplace else!" Intervened Pen. "If I were you I could… I don't know… put it in my shorts and Bam! Crown shorts!"

Ice Prince just widen his eyes at those words and then clenched his left fist, he had heard those words before! But where? He tried to remember where he had heard that and why they made him feel anger. But his inquiry was met by the same pain he felt when he tried to remember certain things, like his dreams. Or why that blond woman that was Pen's mother felt familiar.

The room stood silent for a minute, with the prince trying to calm himself and relieve the headache while Pen wondered with he had say something wrong. "Thanks for the idea, but I don't think I'll like to have crown pants." Said a more calmed Prince. Then an idea came to mind. "I got an idea! Just wait for me, ok? While I go to retrieve something." After leaving his guest alone again, Pen turned to Marshall. "That was weird"

"Just thank Glob that nothing bad happens!

"Now that the Ice Prince is well dressed, It's now your turn Pen!" Marshall turned to his short friend. "Now get inside the closet and change"- Pen just crossed his arms and looked at Marshall defiantly. "Why should I?"

Marshall walked to the young boy and rested his hand on Pen's shoulder. "Because, despite being good clothes for adventuring, yours aren't exactly good for partying… more specifically the time of party I planned. Besides, a little change won't kill you" – Pen took a glance at himself and nodded "Ok, but my hat stays on!" Marshall chuckled and playfully patted Pen on his head. "Sure thing, kiddo!"

Marshall waited patiently for Pen, when the Ice Prince came back. His crown now not on his head but tied to his belt with a chain on the side. "How about this? Does it look better than crown pants?" Marshall nodded and replied "Well, that's better than on your head. We can say that you wear it as a fashion statement".

"Ok Marshall, How do I look?" said Pen after opening the door once more revealing his new clothes. Instead of his light brownish T-shirt and brown shorts, he was wearing a black t-shirt that seemed a size larger but still looked good on him; he also wore khaki cargo pants and kept his brown boots and yellow hat.

"You look great! Dare I say cool" replied Marshall. "What about you Marshall? Are you going to change too?- asked Pen. "Nah! I looked great already." Marshall gave a look to his clothes; a wine colored medium sleeved shirt and jeans. "But maybe I'll take a jacket if you don't mind I.P." The prince just nodded and said "Of course, I don't wear these clothes unless I'm pretending to be someone else.

Marshall just gave him a strange look; he didn't want to know what the Prince did on his spare time when nobody watched him. After taking a black leather jacket, Marshall turned to the Prince. "Now that you mention it. What do we call you? We can't keep calling you Ice Prince or the disguise won't work." The Prince brought his right mechanical arm to his face, pondering. "Also, that pincer hand is a dead giveaway, you should change it too."

"Right, right! Let's go my cupboard in my living room then!" The trek from the Prince's room to the living room was a very fast one. It didn't take more than a minute or two. The Prince opened the cupboard and started sorting all his arms.

"Let's see… tapping arm… no… sword arm… no… fishing pole arm…..no..no,no….Aha! My new five fingers arm!"(1) – He took it out and changed it with his current pincer arm. The Pincer arm was his favorite, it felt the most nostalgic and familiar, also it was perfect as an intimidation tool and to strangle victims (not that he ever did that to anyone).

"How about now?" asked the Prince. "Better than the pincer but maybe we could conceal it with a glove of something."

"Here I have one right here!" said Pen, giving the Prince a black glove he drew from his backpack.

"Fine, now that that's settled, what about a new name?" The Ice Prince just shrugged his shoulders. "What about just Prince? Prince is a name" – Marshall shook his head negatively. "No, too lame and easy to figure out your identity." –

"How about this!" he cleared his throat and said in a less raspy voice. "Hello! My name is Davey. Davey Johnson. Nice to meet you!"

Both Pen and Marshall were amazed by this. He really looked like a different person. "Ok, Davey! Ready to PAR-TEY?" asked excited Pen, almost forgetting he was talking to the Ice Prince.

"Yes! Let's go!" said Davey.

Author Notes:

(1) This arm is just a normal metal arm designed to look as closely as a normal arm. It doesn't have weapons or hidden compartments.

This was fun to write, I don't know why. Maybe because I can deviate from the cannon and add more character development.

Speaking of character development, this next Arc will have a focus on Marshall Lee; He is so fun to write! Don't worry, the Prince will have his scenes too. It is his wedding after all.

Also I feel I have been neglecting Bartram. So he will accompany our heroes (initially he wasn't going to). What do you guys think? Do you want more Bartram? Tell me in a PM or in a review.

Another thing: I realized that Pen's parents don't have names, and since I'm bad at naming characters. I'll ask you to suggest some names for Pen's Parents.

For Pen's mother I came up with these(something with the letter P): Pam, Pepper, Pearl, Polly.

For Pen's Father something with the letter M: Mike, Max, Mark.

If you like one of these or you liked another, please leave a suggestion for the Mertens' names.

As for Wildberry Princess; I thank you all for voting, and if haven't done it already please do. The voting will close after this arc ends.

Remember 1 vote for Person. Send me a PM or leave your vote on the review.
