We open to science class where we see Mrs. Hertz laughing and the rest of the class staring at her.
"I've never seen her laugh so much." Ulrich said.
"I've never seen her laugh at all." Tsuyu said.
"The gas I've just inhaled in a small quantity is called N2o or those of you interested in chemistry know it better as laughing gas. You can see how this gas is used to relax patients in hospitals to prep for surgery." she said.
"What a bad idea. Nothing like a laughing attack after an appendix attack." Odd quipped.
"Let's just try and stay serious because taking it in large doses, it can be highly toxic causing fatal attacks on the nervous system. Only one thing can stop it: water. Water neutralizes the gas right in its tracks." she said as she drank a glass of water from the sink. "Now please get out a piece of paper for a surprise test."
After class, the group gathered on the quad and noticed Yumi was ignoring them.
"Okay, this is the third day she's gone and ignored us. What gives?" Eijiro said.
"Cut her some slack. Her parents are going through some...problems right now." Indigo said.
"Really? Wow...that has to be rough." Asta said.
"It's pretty rough for anyone to be in the middle of a fight between their parents." Hope said. "I feel sorry for Yumi and what she's going through."
"Yeah, lemme see if I can talk to her." Ulrich said going to Yumi.
"You think Ulrich can get Yumi to smile?" Jeremie asked.
"About as much of a chance as Luffy being able to swim, which is never." Genis said.
"Hey, Yumi." Ulrich said.
"Leave me alone. I don't feel like talking." Yumi said.
"But I feel like talking." Ulrich said.
"Then talk to yourself." Yumi said as she left without saying another word.
"Come on, Ulrich. There are better girls than Yumi." Sissi said arriving as Ulrich started to leave. "Wait! Are you coming to rehearsals tomorrow?"
"I'm going for Odd, not you." Ulrich said.
"Don't forget it was me who got Odd to play the music. I think you would be perfect to play Romeo." Sissi said.
"And let me guess, you're Juliet?" Ulrich said.
"What do you think?" Sissi asked.
"I'll think about it." Ulrich said as he left.
Meanwhile in the science building, a large cloud of black smoke appeared and flowed to the laughing gas. It entered the containers and flowed out a large purple cloud with a smiling face. Meanwhile just a bit outside the city at night, a new creature was looking over the city.
"So this place is where Dracozolt got tricked by some humans? Heh. I'll show them what happens when you mess with our little family." they said laughing as they headed into the city.
Later…
Ulrich went to Yumi's house and knocked on the door. After he knocked, Mrs. Ishiyama arrived at the door.
"Hello?" she asked.
"I wanted to talk to Yumi." Ulrich said.
Later in Yumi's Room…
"So, where's your dad?" Ulrich asked.
"Staying with a friend from work." Yumi said.
"So what was that fight about?" Ulrich asked.
"I don't really know. My mom tried to explain it to me, but I don't think she knew why either." Yumi said.
"Those kinds of arguments are the worst." Ulrich said.
"I'm really glad you came. Thanks Ulrich, for cheering me up." Yumi said.
She then gave Ulrich a rose before sending him off as he smiled.
Back at the Sunny…
"One of those cases, huh? Well, that figures." Captain Cold said.
"Was it the same for you and Barbara back in Paris?" Cia asked.
"Actually, it goes a little further than that. You see, sometimes, when emotions overflow, they tend to come out in different ways." David said.
"It's a wonder that we never fight like that. Well, almost never." Hagakure mentioned.
"Yeah...things have been a bit more tame for awhile now." Jexi said.
"There's no telling when XANA is going to launch an attack." Zelos said.
"Speaking of which, I'm thinking we should go for Violight first." Himeno said.
"Violight, huh? I promised Dracozolt we'd have a fair fight there." David said.
"Jexi, you went for Violight first when you went through this, right?" Fulgore asked.
"Yeah but that was cause they had a captive last time. Things are different this time around. Though...we should keep the idea of attacking them open in mind." Jexi said.
"In the meantime, David, I would suggest going back to sleep. You have a big day tomorrow, after all." Fulgore said.
"It's kind of hard to, Odd and the others are rehearsing for the big play." David said.
"Hey, we can wake you up if you're worried about missing the show. Just get all rested up, dude." ZS assured.
"Don't worry about me. I'll be fine. Thanks for the gesture, though." David said as he hung up.
The next morning in the auditorium the cast began to practice for the big night. As Odd began to play his guitar and the cast was rehearsing, the purple smoke then entered Odd and he began to laugh uncontrollably.
"Oh come on. It wasn't that bad." Herb said.
"Odd! I'll show him a thing or two." Sissi said. Sissi then grabbed a water bottle and poured it on Odd and the smoke left him and entered the air vents. "And don't bother showing up. This is a tragedy, not a comedy!" Sissi said as she left.
"Hey, wait!" Odd shouted.
"Hehehe." Miles said laughing a little before Mina dumped water on him. "What the heck? I just found the last part of what she said amusing."
"Yeah. It was pretty good. But Odd never laughs like that...especially during a drama like this." Mina said.
"Unless...he inhaled nitrous oxide." Miles said. "We might need to bring this up with the others."
It was later in Jeremie's room…
"And when Sissi dumped water on me, I felt okay and stopped laughing." Odd said.
"It sounds like symptoms of intaking nitrous oxide. It could be a XANA attack." Jeremie said.
"No doubt about it." Genis said.
"Let's make sure." Raine said.
They went into the science room and began to inspect the cannisters.
"Just as we thought. All of these are empty." Miles said.
"But...it's just laughing gas right? Not like it can cause real harm." Rainbow said.
"Maybe in small doses, but too much causes damage to the nerves and could cause the subject to die of oxygen deprivation." Miles said. "And since he's possessed several canisters worth, he's literally a cloud of laughing death."
"That doesn't sound very good." Genis said.
"Don't worry. We'll head to the factory and deactivate the tower. And with enough time to catch Romeo and Juliet." Mina said.
"We'd best get moving, then." Raine said.
"Yeah. If Violight makes a move, I'm sure the others can handle it." Genis said.
They hurried off to the factory before seeing a thick layer of ice covering the bridge.
"What the? Did someone ice the bridge?" Rainbow said.
"Damn right someone did." a voice said as stepping out was a creature with a bird like head and arms and a dino like lower body.
"It's like that Dracozolt from earlier, but this one is different." Genis said.
"Bzzt! Arctozolt, the Fossil Pokemon! An Electric and Ice Type! This Pokémon lived on prehistoric seashores and was able to preserve food with the ice on its body. It went extinct because it moved so slowly." Rotomphone said.
"Okay, kids. I promise this won't take long. I'm just looking for the idiot who went and messed with my brother, Dracozolt's, head." Arctozolt said.
"You mean David, right? First of all, he didn't mess with his head at all." Genis said. "He only challenged him to a fair fight with no distractions."
"Yeah...that's not gonna happen. Look, my brother has a lot of issues with his body and doesn't need to be fighting or getting into fights. So I came looking for you so you'd call it off." Arctozolt said.
"That's not for you to decide. Besides, Dracozolt has already agreed to it." Raine said.
"Please, he'll just forget about it by tomorrow anyway. Just call it off." Arctozolt said.
"She just said it's not for you to decide." Genis said.
"Okay...fine. New plan." Arctozolt said freezing the surrounding area to make a sort of arena. "Instead of facing him...you'll be fighting me instead."
"Are you sure? I mean...you look a little slow getting around." Rainbow said.
"Definitely sure. I win, you call it off. You win, I'll drop the subject." Arctozolt said.
"Geez, overbearing much? Fine, we accept your terms." Genis said.
"Perfect. So...let's go! Bolt Beak!" he said, sliding at them with an electrified beak.
"Fire Ball!" Genis said shooting fireballs at Arctozolt.
"Gah! Oh now you're really gonna get it! Blizzard!" Arctozolt said unleashing a blizzard at them.
"Stone Blast!" Genis said as rocks started to strike Arctozolt from underneath.
"Okay...another lucky hit but I can take it. Have this! Ancient Power!" Arctozolt said weakly firing several large rocks.
"You sure you can handle this? You're starting to lose a lot of energy." Genis asked.
"No...I can...I can…" Arctozolt said falling to the ground. "Would you be cool with...calling it a tie?"
"I'm afraid that's not how these things work. Now, if you'll excuse us." Genis said.
"Damn…" Arctozolt said before collapsing.
The group soon reached the factory.
"We need to hurry. The show is going to start soon, and so will XANA's strike." Raine said.
"Okay. Odd, Genis, Raine. This one is all for you." Jeremie said. "Here goes. Transer, Odd. Transfer, Genis. Transfer, Raine. Scanner, Odd. Scanner, Genis. Scanner, Raine. Virtualization!" Jeremie said sending the three inside.
"So, this is what it's like inside a virtual world. Truly fascinating." Raine said.
"Yeah, you get used to it." Odd said. "Now come on. Aelita's waiting and the tower shouldn't be too….far...away?" he said as they found themselves standing outside a large labyrinth surrounding the tower.
"It's like a maze. We just need to find the right path to the tower." Genis said.
"Yeah. Or...Jeremie...mind finding us a path? Jeremie?" Odd asked only to be met with silence.
"No response. You don't think the gas has already gone through, have you?" Genis asked.
"But there's no way for it to...the ventilation shafts!" Raine realized. "No...we can't worry about that. As long as they get to a source of water, they should be fine."
"But if he leaves the supercomputer, then there will be no one to launch the return to the past when we finish." Genis said. "N-never mind, we'll figure something out once we're done."
"For now...let's try and get through." Odd said as they hurried on inside and started to puzzle their way through the labyrinth bit by bit.
"Odd...are you feeling okay?" Genis asked.
"Yeah...yeah. I'm fine." Odd said feeling a little woozy. "Okay...maybe not. Something must not have gone right with my transfer."
"Oh no… Some of the gas must've leaked in. We need to finish this fast." Genis said.
"No...you two...need to get Aelita to the tower. I'll just slow you down." Odd said.
"Odd, you shouldn't say stuff like that." Genis said.
"It's true. I can feel myself getting weaker. But it's okay...I had a vision. I saw the route to the tower." Odd said.
"You have?" Genis asked.
"Yeah. Take the next left and then go right three times and you'll be there. Also...Genis...you're gonna have to take out Raine once Aelita goes inside." Odd said.
"Right… Someone has to launch the Return to the Past." Raine said.
"Just make sure not to breathe in the gas on the way there." Genis said.
"I won't." Raine said as they hurried off with Aelita while leaving Odd behind.
They soon reached the tower as Aelita went in.
"Ready, Sis? Here we go… Wind Blade!" Genis said as he sliced Raine with a blade of wind, devirtualizing her. Once she got out of the scanner, she covered her nose and mouth so she wouldn't breathe in the gas on the way to the supercomputer.
"Okay. I've seen Miu and Jeremie do this plenty of times." she thought as she entered the sequence. "Okay. Return to the Past, now." she thought as a flash of light spread. Once it subsided, they were watching the play as it unfolded before them. Ulrich had just finished his part and went behind a fake bush. But as he did, the group behind the curtain pulled up the bush revealing Ulrich and Yumi together causing the audience to laugh, including Yumi's parents.
"Well...looks like everyone gets their happy ending." Usopp said.
"Yep. I'm just glad things are better between Yumi's family now." David said.
"Yeah...they're one big happy family again." Hope said.
