Now…. On with the show!

Jim followed Snotlout, Fishlegs, and the twins into their "Dragon Dome". It was an arena with an interesting mechanism that allowed the doors to slide shut into a round dome by merely cranking a lever, and although it was a bit smaller than the training arena Jim used back home, it still wasn't bad.

Tuffnut was cranking the doors all the way open, allowing sunlight to stream in from three directions. It was large and spacy, quite nice all in all.

Jim looked up at the where the three wooden beams met above, and he glanced about in awe at the entire contraption around him. Considering that he was in the "Viking Age" where the quite obviously didn't have phones or electricity or any of the other complicated conveniences of the modern world, it was quite amazing to see such complex creations.

"How did you make this?" Jim asked as he continued looking about, walking over to one of the folded walls and knocking on the strange bendable medal.

"Hiccup came up with the design." Tuffnut explained. "He always does. Show off." He muttered.

Jim wasn't entirely sure how to take that, either that Hiccup was a mind genius- the Viking age Einstein if you will- or if he was just as Tuffnut had said- A show off.

Somehow Jim doubted if he was a show off in this case, because from what he'd seen/heard from and about Hiccup so far, Hiccup was a really nice and humble guy. Not one to brag. Heck, he didn't even mention his supposedly flaming sword! Tuffnut had to be the one to bring it up, and Jim doubted if Hiccup would've ever even mentioned it if it hadn't been already said.

"It's amazing." Jim murmured, turning about in a little circle so he could view the entire length of the dome.

"Yep." Snotlout said proudly, leaning up against the beam. "Hookfang and I did almost all the pounding of the Gronkle Iron, right Hookster?" his dragon- which Jim had learned was a Monstrous Nightmare named Hookfang (again… WEIRD NAMES! But cool none the less)- huffed before lifting his horned head high in the air, closing his eyes and striking a powerful pose.

"Yes, but if it wasn't for my Meatlug, we wouldn't even have the Gronckle Iron!" Fishlegs said as he along with his pudgy dragon entered the dome. "Snotolout loves to hog attention." He explained quietly. Claire gave a snort of laughter.

"I do not!" Snotlout huffed irritably.

"Guys, come on, try not to argue, okay?" came the sound of Hiccup's voice from behind, so Jim twirled about to see he and Astrid stepping into the stone dome, Hiccup holding a strange cylinder contraption in his hand.

How is that a sword? Jim thought in confusement, but he shrugged, knowing that somehow it would work. He peered a bit harder at it, and realized with some amusement how it almost looked like a lightsaber… Just a bit bulkier and had what looked to be Dragon's carved onto the ends.

"I don't know about this." Hiccup said nervously, shifting his contraption from hand to hand. "Somebody could get hurt…"

"You afraid!?" Snotlout called out, a smug expression planted on his face. Tuffnut whistled while Ruffnut clapped her hands excitedly, glancing from Snotlout to Hiccup then back again.

Astrid growled angrily before marching over to Snotlout and grabbing his arm. For a second Jim thought she was going to drag him out of the dome, but to his surprise and shock she merely and effortlessly flipped him over onto his stomach against the stone ground.

"Go on!" She shouted. "I'll take care of this mutton head."

Hiccup stepped closer across from Jim with a little sigh, and it was clear he was nervous. Claire and Toby stepped over to Astrid and the others, all turning to watch the show. Toothless stepped up beside them, his expression betraying amusement. He let out a vibrating coo, earning a small chuckle from Hiccup.

"Thanks, bud." He teased, gripping that strange contraption a bit tighter in his left hand. Jim hung onto Daylight with both of his, but it was directed more to his right hand since that was his sword fighting hand. It confused him for a moment that Hiccup was fighting left handed, because Jim had personally never actually sword-fought a leftie before.

"Err…" Jim said awkwardly. "Suppose we don't have a choice, huh?"

"Nope!" Came a shout from the crowd.

Hiccup rolled his eyes and shook his head. "Well, let's get this over with." He said nonchalantly, clicking his finger against the cylinder. Jim involuntarily jumped back when a blade slid out, the sudden movement nearly knocking him off balance. Hiccup laughed and gently waved his hand a bit, flicking the sword with his wrist. "What do you think of it?" He asked with a bit of embarrassment. "Still trying to figure all the mechanisms out… I want to try and make it so I don't run out of Nightmare gel…"

"No! It's-It's amazing!" Jim exclaimed. "How… I just don't get how you make all this stuff… especially without electricity or construction equipment. It's awesome!"

Hiccup looked mildly puzzled, so he just shrugged and grinned. "Ehh, still needs some work… but thanks."

"GET ON WITH IT ALREADY!" Snotlout exclaimed from his place on the ground, Astrid's foot still planted firmly on his back.

"Yes!" Tuffnut agreed, looking excited as he did a little tap of his foot. "I must see something soon!"

Jim laughed and extended Daylight before him, urging Hiccup to do the same. The two began to circle each other, Jim waiting for Hiccup to make the first move so he'd know what sort of technique he used.

But Hiccup seemed totally relaxed and patient, not looking antsy or nervous at all. Jim on the other hand was as nervous as could be, taught and rigid. He knew he needed to relax- like Hiccup was- but he found it almost impossible. He was fighting a Viking for goodness sake! Viking's were known as these fierce weapon loving men and women, with loads of muscle and brute force to match.

Jim gave Hiccup a quick look over, realizing that he probably didn't have to be this… afraid. Hiccup definitely wasn't all muscle and brute force like Jim had read in the history books, he seemed more like the brainy type, the one who liked to think things through and settle things with words rather than force.

But that didn't make Jim any less tense. Snotlout definitely had some of the brawniness a Viking should have- or at least a Viking from the history book should have. And then there was Astrid, and holy cow could that girl inflict some injuries! She looked like she could take them all down with one hand tied behind her back… and he hadn't even seen her use the axe yet.

It had been almost three minutes, and they were still circling each other. Jim was beginning to get even more nervous as time passed, wishing Hiccup would just lunge already and make the first move. But Jim's opponent didn't seem to be in any hurry, and didn't look bothered by how slow this was either.

Finally, Jim just couldn't keep his calm. He lunged forward and clashed Daylight against Hiccup's sword, faintly in the back of his mind wondering why it wasn't on fire. Wasn't it supposed to be a flaming sword-?

His question was answered, for Hiccup switched a button on the handle of his foldable sword with a small click, and instantly the blame licked with fire. Jim jumped back in surprise and shock at the sudden heat.

"Woah!" He shouted as he dodged a swift swing from Hiccup's sword, the fire stretching out from the blade as Hiccup spun about, creating a fire circle about himself. "Woah, woah woah!"

"Duck, Jim! It's just a little bit of fire!" Toby called out while hopping up and down excitedly.

Jim ducked when Hiccup made another swing, then he reached a hand out and recovered Daylight, making his own swing towards Hiccup when the one-legged Viking stepped backwards.

But, much to Jim's surprise and bewilderment, as soon as he swung Hiccup lunged and ducked, somehow flipping over and landing behind Jim. He stood there for a moment, stunned by what had happened before snapping back to his senses and flipping around to try and drive his opponent back.

Too late. Hiccup flicked his sword, which was now clutched in both hands, and he clashed it against Daylight's handle, instantly making it disappear from Jim's hands. Jim stared at his empty fists for a moment, before grinning up at a bewildered Hiccup, who was slowly letting a smile light up his face.

Silence fell for nearly a minute, a silence worthy of the "pin dropping" description.

"Oh my THOR! DID YOU SEE THAT!?" Tuffnut shrieked, burying his hands in his dreadlocks. "I can't believe Hiccup actually won!"

Astrid smirked and removed her foot of Snotlout's shoulder blades, instead walking over to Hiccup and wrapping her arms around him in a quick hug. "I knew you could do it! And you were nervous…"

Nervous? What does he look like when he's calm? Jim thought with a shake of his head. Hiccup had been as calm as a cucumber… wait was that even a saying? All Jim knew was that Hiccup had appeared to be as calm as could be, and nervous was definitely not the word he would've used to describe him.

Hiccup grinned at Astrid before turning back to Jim and clicking the sword, retracting the blade before offering his hand in a friendly hand-shake.

"Heh, I-I thought I was dead…" Hiccup laughed nervously. Jim laughed along with him as he grabbed the hand and gave it a firm shake, releasing it and holding out his hand so Daylight could reappear.

"I've never fought someone with a fire blade before!" Jim exclaimed excitedly. "That thing is so cool! How-How did you make it?"

Hiccup opened his mouth to reply, but Astrid answered before any words could be said, "After many, many, many MANY test tries and reruns and re-designs..."

"I've had it designed for a while now… almost a year." Hiccup explained, and Jim couldn't help but notice how he absently wrapped an arm around Astrid's waist, drawing her a little closer. Jim smiled to himself when he saw that Astrid seemed oblivious to it- well, not entirely for she wrapped an arm around his waist in return. But it all looked so natural and laid back, like neither really realized what they were doing. It made him daze out a moment, wondering if he and Claire would ever get that close…

"Jim!" Toby shouted, scuttling forward till he skidded to a stop before him. "You let him beat you!"

Jim laughed and grabbed the amulet, letting his armor fall way so he was once more in his comfortable cloths. "I didn't let him, Toby. He beat me. Heck, I was trying, but that sword! And he's a leftie! And he's just darn good…"

Astrid chuckled, glancing up at the boy by her side. "Keep it going, Jim, he's blushing like crazy now."

Claire skipped up beside Astrid and grinned at Jim. "I think you need more practice." She stated. "Maybe Hiccup would give you some lessons..?"

Hiccup was as red as a tomato now, and he lifted his free arm to wave in a wild gesture. "G-guys… seriously I-I couldn't… I mean-Astrid-"

Everyone burst into laughter at his stuttering, Snotlout and the twins laughing so hard that they had to wipe tears from their eyes.

"Oh, gods, Hiccup, you're such a dork…" Astrid chortled, wrapping both arms around Hiccup again.

Jim was about to say more, when he heard a loud whoosh! come from behind him, causing him to jump in surprise before stumbling about to see what it was.

To his surprise and shock, Blinky suddenly faceplanted out of thin air onto the stone ground. Not a second later Argh followed, landing with a crash on top of an unfortunate Blinky.

"Argh! Might you please get off of me? Cutting off the air supply!"

Argh tapped Blinky on the head, and both trolls looked up at the stunned and shocked expressions of the Trollhunters and the even more bewildered Dragon Riders. The two groups just blinked at each other for a moment, before Toby let out a whoop and dashed forward, wrapping an arm about Argh in a stone crushing hug.

"Blinky!? Argh!?" Claire exclaimed, stepping forward and bending over so she could see Blinky a bit better.

"What are you guys doing here!?" Jim shouted in surprise, running forward and helping Toby with getting Argh off of a breathless Blinky. Once done Blinky got to his feet, all four of his hands going to dust himself off.

"Hello, Master Jim!" Blinky greeted while Jim impatiently waited for him to explain. "And hello strangers whom we've never seen or met before! And- OH MY BRITCHES IS THAT A DRAGON!?" He rambled quickly, and once catching sight of all the Riders dragons doing a double take, stumbling back towards Argh.

"Is… is th-that a-a-a…" Tuffnut stuttered, lifting up a hand slowly to point at both trolls. "T-t-t-t-t-t-r-r-r-ol?"

Jim sighed and placed his fingers on the bridge of his nose, wondering if they'd ever make it home now. "Hiccup, Astrid, guys, this is Blinky and Argh." He gestured to both said trolls, who offered waves.

"Hello." Argh said in his deep rumbly but friendly voice. He gave them a happy smile, although the Riders were still frozen in place with shocked expressions seemingly glued to their face. Jim was beginning to wonder if Snotlout would ever pick up his jaw of the ground or if he intended to walk around like that.

"Argh, Blinky, this is Hiccup, Astrid, Snotlout, Fishlegs, Tuffnut, and Ruffnut." He introduced, pointing to each rider as he went. He paused at the twins, only remembering who was who by the different hair styles. "…And their dragons." He pointed over to the dragons, who looked just as stunned as their riders. Toothless snapped out of it first, offering a cautious growl before relaxing and plodding over to sit beside Hiccup, wrapping his tail about his rider's feet protectively.

"Oh, Master Jim this is amazing!" Blinky praised, tapping his hands together. "Oh, so nice to meet you all!"

"It's a troll…" Snotlout whispered, finally finding his voice. "A REAL LIVE TROLL!"

Jim rolled his eyes and laughed, "No Snotlout, it's a mouse."

"Actually, mice are rodents, we are in fact made of stone." Blinky explained tapping himself for emphasis. He then glanced outside the dome, giving a worried look about. "Um, the sun…" he explained, waving a hand towards the bright light streaming inside. Thankfully, the trolls had collapsed into a shaded area part of the dome, covered by the piece of medals that made the dome a… well… a dome.

"Sun…?" Hiccup croaked, looking bedazzled by everything happening.

"Trolls can't be exposed to sun." Jim explained, looking about for that lever Tuffnut had cranked earlier. "They'll turn into stone…"

"Aren't they techniquely already stone?" Claire joked, but helped him with the lever. Finally, they had it switched, and the dome began to slide shut.

"Alright, now Blinky." Jim turned and crossed his arms, striding over to the troll and giving him a withering look. "WHAT IS GOING ON!?"

"Yeah, why you guys here?" Toby asked, as though that thought hadn't occurred to him until that moment.

"Well." Blinky began. "The good news is, we discovered a way to get us all back home!"

Jim sighed and let himself relax, "Oh thank goodness for that-"

"Yes, I thought you'd be happy!" Blinky said with more clapping of his hands. "Now." He turned around and stuck his arm into the air, half of his arm disappearing from sight. "Ha, so here's the portal, let me mark the spot so we don't forget it!" he quickly scratched a mark on the ground, stepping back with a satisfied nod of his head before turning back to the others.

Tuffnut let out a squeal of excitement before barreling forward, ramming right into Argh and giving him a huge hug. But, since he didn't realize how hard a troll really was, he instantly bounced off and stumbled backwards, looking rather dazed and faint.

"Holy yak, Ruff! Check this out! He's like a walking rock!" He walked back to Argh, tapping the troll with his fist before grabbing his helmet. "This is amazing!"

Snotlout followed Ruffnut and Snotlout over to a shy Argh, who was trying to back away but failing to. Snotlout knocked against Argh's arm with his hand, looking on in awe. "Do you feel that?" He asked, giving Argh another hard rap with his knuckles.

"Not much." Argh answered deeply.

"Have they not seen a Troll before?" Blinky asked in amazement. "This is a great discovery, Master Jim! The Trolls must be in hiding already!"

"When can we leave, Blinky?" Claire interrupted, putting on a serious tone. Leave it to Claire to be the calm and sensible one, Jim thought with a smile. Even though Claire wasn't "his" girl, it still brought him pride to see her act mature beyond her age.

"Anytime, Claire." Blinky replied with a soft smile. "Do you wish to leave already?"

"Well… the sooner we get back the sooner we can get to work getting my brother back." Claire said hesitantly.

"No, you guys should stay the night!" Astrid insisted, stepping forward hesitantly, eyeing Blinky wearily. "We could have a banquet tonight, then a sleep over or something… that alright, Hiccup?"

"Yeah, yeah! That's totally fine! You guys have only been here for a few hours." Hiccup agreed, his prosthetic making little clinks against the stone ground as he stepped closer. "Then you guys could either leave tonight or tomorrow if you want.

"Tonight." Claire said firmly, and Jim winced at the worried tone she used. "I mean- because we need to figure out… so we can my brother back…"

"I get it." Jim reassured her. He turned back to Hiccup and Astrid, who were both wearing uncertain expressions. In the background, Argh was lying on his back while he took turns tossing Snotlout the twins and Toby up into the air.

"Sorry, but we have to leave sooner than later. I don't want Mom to worry either…" Jim added, realizing that yes, leaving tonight would definitely be the better choice. "But we'd love to stay for supper!"

"Supper!?" Toby called out as he flew through the air. "Food!"

"Is that alright with you, Claire?" Jim asked, not wanting to maker he feel like they had to stay. If she wanted to go then he was more than happy to consent… if it meant she'd be happy.

"Yes, that-that sounds like fun…" Claire finely replied with a smile in Astrid's direction. "Maybe you could teach me some of your moves?"

Astrid laughed and nodded, "I'd love to!"

"Alright, so we'll stay until tonight and we'll leave after supper." Jim decided. "This should be fun!"

I know there are typos, but I'm too lazy to go back and triple check (I quickly scanned through it, but I'm pretty sure I missed a couple…)

Anyways, next chapter should be the last one… see ya then! :D
