Hey, guys. Here is another chapter of this story. I just finished playing Naruto Shippuden: Ultimate Ninja Storm 3 last week, and I have time to write this chapter.

Thank you for waiting, and now here is the new chapter. Hope you like.


Chapter 14: Darkness Rising, Part Four

"Megatron has desecrated the resting place of our fallen ancestors... and his own!" Ratchet said as he got into a fighting stance.

"Not even the dead are free from his warmongering." Optimus added mournfully.

From the top of the cliff, Megatron stares down at the scene as he enjoys the feeling of Unicron's dark power flowing through his body. "At last, symbiosis. I can feel it. I possess complete control over my army. Destroy them!" Megatron commanded to his undead warriors.

Optimus began shooting at the incoming horde of zombies while he and Ratchet began backing away. It seems that shooting at them doesn't seems to work as they keep on getting back up. "Optimus, if our combatants are already deceased, how can we possibly defeat them? And don't say 'Shoot them in the head'. That only works on Sam's movies." Ratchet added with a small humor.

"Ratchet, retreat! Bridge yourself back to base!"

"No, I shall stand with you, Optimus." Ratchet took out his blades and stood beside Optimus. "Sam will have my head if I leave you here fighting against these monsters all by yourself."

Optimus gave a tiny smile behind his battle mask at the mention of Sam worrying for him. Ratchet charges at the Terrorcons and began slicing the Terrorcons and dodging each blow they can give out at their slow pace. Ratchet saw a twitching dismembered arm have stopped moving and its purple glow seems to fade out as well. "I recommend dissection. The smaller the pieces, the better." He advised. "And Sam says that the only way to kill a zombie is to shoot them in the head. Wait till I prove him wrong." Ratchet said smugly.

Optimus gave a small roll of his optics before withdrawing his cannons and took out his blades and began slicing down the Terrorcons along with Ratchet.

"I have mastered Dark Energon. When you fall, Optimus... You too shall join my army." Megatron proclaimed.

Optimus narrowed his optics at Megatron before slicing more Terrorcons at a fast pace.


The three Vehicons from above began shooting at the three boys whom has unknowingly entered Decepticon territory. The boys dodged every single shot that the Vehicons fired. One blast threw Sam to the ground while trying to protect Rafael. In an instant, Jack rushed to Sam's and Raf's side and protected them by covering them with his own body.

Bulkhead appeared in front of the three boys and opened his door. "Get in, now!" He yelled. They didn't need to be told twice as they quickly got in. Bulkhead quickly drove away, evading from the attack.

"Nice timing, Bulk." Sam sighed in relief.

"Thanks, Bulkhead." Jack sighed as well

"Yeah, thanks." Rafael agreed.

"Wh-what are you doing here?" Bulkhead demanded with a bit of frustration.

"We were worried about Miko. Have you seen her?"

"What's she look like?" Miko joked as she popped out from the backseat.

Bulkhead slid behind a huge boulder and opened his door. "Everyone out! And this time, please wait here." He pleaded to the kids as they got out of the vehicle. Once they are out, Bulkhead drove towards the Nemesis ship. Bulkhead jumped and transformed back into his robot form and grabbed on the cliff. He scaled up the cliff and climbed aboard the Nemesis. Bulkhead smashed a Vehicon and used that same Vehicon as a shield to guard himself from the incoming attack. Bulkhead blasted the 'Con off balance before body slamming the Vehicon.

He looked over the ship to make sure the kids are safe from harm. But there was one missing from the group. "Where's Miko!?" He asked. He felt something banging in his chest and opened it only to have Miko pop up from his chest while taking a huge breath of air. "Miko?"

"I heaved on your floor mats. Sorry." She apologized before covering her mouth to prevent from throwing up again. Bulkhead helped Miko out of his chest and placed her on the floor. "Remind me never to do that again."

Before Bulkhead could scold Miko for her stowaway, he was tackled by a Vehicon. Bulkhead easily overpowered the 'Con and flipped him over and punched him to death. He looked up to see more reinforcement headed his way. Bulkhead tore off the ship's satellite and threw it at the incoming Decepticons. Bulkhead picked up Miko and rushed to the open hatch of the ship and jumped in.

Back at the three boys, they are feeling uneasy as they hear the sound of gunfire ceased. "Think they forgot about us?" Rafael asked. His question was answered when three Vehicons showed up behind them and captured them.

Bulkhead ran through the hallway of the ship to find where the 'Cons are keeping Fowler prisoner. He picked up the pace when he saw Miko trying her best to keep herself from heaving again. Up ahead, he spotted two more Decepticons and the two spotted them as well. He slid Miko right underneath them while Bulkhead punched the two Vehicons.

Miko yelped when she came to a halt. "I'm gonna heave again." She proclaimed. She was quickly scooped up by Bulkhead and the two continue to run.

In a different corridor, three Vehicons walks down the hallway with the boys in their hands. Sam felt his heart hammer in fear as he looks around the familiar hallway. He never thought that he might find himself captured again and taken back to the warship and probably experimented again. Surely, the Decepticons already knows of his mysterious revival back from the dead and was also ordered to bring him back to the lab alive. He began trying to squirm his way out, but no such luck. The 'Con that is holding him has his arms pinned.

"Take the two to the brig." One of the Vehicon ordered. "Commander Starscream is keeping the other human there."

"What about this one here?" The Vehicon raised up Sam.

"Take him back to the lab. Lord Megatron wants him back there once he's captured again."

The Vehicon nodded before he went to the other direction, taking Sam along with him. They didn't get far as Bumblebee and Arcee came knocking over the Vehicons. Arcee quickly transformed into her robot form and caught Jack and Rafael from falling while Bumblebee did the same with Sam, then pulling him close to his chest after he caught him.

"Appreciate clearing the front door for us, but storming in the Decepticon warship was not in the activities list." Arcee scolded the boys.

"Well, it is now." Sam remarked. "Including rescuing Fowler."

Arcee gave a glare before they all began running down the corridor to search for Fowler. When she got to the corner of the hallway, she leaned to the wall with her weapon armed and ready. She turned around the corner and pointed her gun at the newcomer.

"Friendly!" She yelled quickly.

"Hello!" Bulkhead greeted, with his cannon aiming as well.

Arcee sighed in relief. "Brought the humans, huh?"

"You try getting them to stay behind." Bulkhead whined.

"In any case, we need to find Fowler and get these kids out of here."

"He's in the brig." Jack informed.


Fowler became weaken by the torture Starscream has giving him. He could now say that he now knows how Sam felt when he was captured by the Decepticons. But this is nothing in comparison from what Sam went through. Even so, he is not going to break. No way in Uncle Sam's beard is he ever going to give in to the pain and torture. He will remain strong, for Sam. No way will he tell the 'Cons the location of the 'Bots' base and have them lay their metal finger on his grandson again.

"My dear Agent Fowler." Starscream enters the room with a sickening smile. "You do realize the Autobots have abandoned you. I am the only one you can rely upon now. So tell me what I want to know... or..." Starscream raised up the Energon prod in suggestion.

Fowler knew that was a flat-out lie. He knows that the Autobots will never abandon one of their own. They have proven him that when Sam was captured by the Decepticons. They had searched high and low for the boy without any pitstop, without any sign of giving up. Even if they did were to abandon him, Sam will surely persuade them to rescue him. He has them wrapped around his little finger.

A distant sound of gunfire was heard from inside the brig and everyone looked at the door. Fowler knew that the Autobots has come to his rescue and decided to have a little fun with Starscream. "They're in...secret government base."

Starscream realized that Fowler is telling him the location of the base and he leaned a bit closer. "Yes? Go on."

"In the old steel mill. Or was it under that carnival funhouse?" Fowler smirked at Starscream.

Starscream snarled in anger, having been played by a human yet again. Starscream gives him a jolt with the Energon prod, stunning him into unconsciousness. "Someone find out what is going on out there!" Starscream ordered the two Vehicon guards.


The door of the ship's bridge was being banged loudly. One of the Vehicon went to go answer it, only to get shot when the door opened. Arcee, Bumblebee and Bulkhead charged inside the bridge and shot all the Vehicons that were inside.

"Clear." Arcee announced as the kids walked inside the room. "Wait here." She instructed the kids. Bumblebee gave a questioning buzz. "They're are slowing us down and the Decepticons are still after Sam. They'll be alright in here, as long as they stay put." With one last look at the kids, the Autobots readied their weapons and left the kids at the ship's bridge.

After the door to the bridge closed, Miko looked back at her companions with glee. "That...was intense." She commented about the battle.

Sam hummed in agreement, smiling. "I know, right? Did you see the way Bulkhead thrashed against that 'Con? That was so freakin' cool! It's been three years since I've seen any intense fighting between Autobots and Decepticons."

Miko glared playfully at Sam. "Man, I am so jealous of you right now! Not only you get to live with the Autobots, but you also get front row seats on the action."

"How about we make it our activities list?" Sam asked Miko. "The next time the Autobots goes on a mission, we tag along with them and see all the action."

"Aw, yeah!" Miko agreed.

Jack couldn't believe what he was hearing. Is he the only person in here that is sane? Well, Rafael is, but not Sam and Miko. They came here to bring Miko back before she gets into any trouble, not encouraging her to do this again. "Sam!" Jack yelled. "We came here to scold her for her behavior, not encouraging her!"

"Fine, fine." Sam sighed before looking back at Miko again with his narrowing eyes. "Miko, what you did was irrational. When you tag along with an Autobot on their mission, you are suppose to stay hidden to prevent yourself from getting exposed to the Decepticons. Do you understand?"

"Yes, sir." She saluted playfully.

Sam was pleased with her answer and turn to face Jack. "There. All done scolding."

Jack stared at Sam with disbelief. "Sam!" He yelled out angrily. "You were suppose to yell at Miko for getting us stuck in this situation!"

"I'm sorry. Did I ask you to follow me?" Miko stepped in with a furious look on her face.

"You wanted us to be a band. Doesn't that usually mean playing together?" Jack retorted.

"Well, maybe I decided to go solo."

"Well, maybe I have some regard for your safety. Unlike someone over here." Jack looked at Sam in which Sam stuck his tongue out at him.

"Oh, I'm sorry, is your name 'Optimus'? You can leave my protection to Bulkhead, thank you very much..."

Their little ranting was cut off by a yell. "Stop it! Both of you!" Rafael yelled before running off and sat on a step.

The others followed him, feeling guilty for upsetting Rafael. "H-hey, Raf, Raf, it's...it's ok." Jack spoke softly.

"Yeah, we're gonna be fine." Miko placed a reassuring hand on Raf's shoulder.

"Our 'Bots will come back for us." Jack added.

"Yeah, they're gonna take us home." Miko said as she rubbed his shoulder softly in comfort.

"How do you know?" Rafael muttered unconvinced.

The others were taken aback at Raf's lack of faith on the Autobots. Sam scootch himself between Jack and Raf before placing an arm around Raf's shoulder. "I should know. Remember when I told you that I was captured by the Decepticons three years ago?" Sam waited for Rafael to nod before continuing. "From what Ratchet told me, the Autobots never gave up on me. Day and night, they never stopped searching for me. They made it their top priority to find me and to bring me back home, to them. After a month of searching, they found me and brought me back home. So when either one of us say that the 'Bots will take us back home safely, you better believe that the 'Bots will bring us back home." Sam said with a smile.

Rafael couldn't help but smile back as well. "Thanks, Sam." He said as he hugged Sam.

"It's nothing, really." Sam hugged back as well.

Miko and Jack smiled, seeing that Rafael is calm now. Jack looked around the room until something caught his eye. "Hey, Sam? You've been living with the Autobots since you were a baby, right?"

Sam looked at him with confusion, wondering why is he asking that. "Yeah. Why?"

"They must've taught you how to read their language, right?"

"Yes. They taught me how to read and write Cybertronian."

"What do you make of that?" Jack pointed at the computer.

Sam narrowed his eyes to get a better look. He jumped down the steps and head towards the computer to get a better look. After he's finish scanning, he groan in frustration. "Damn it! These are advance Cybertronian schematics. I can't read it." He curse Ratchet for nothing giving him advance lessons.

"But are they important?"

"As far as I know, yes, yes they are."


Starscream is beginning to get impatient as the shooting keeps getting closer and closer. "Wake up, you pathetic lump of flesh!"

"Hmm... grandma? Is it cookie time." Fowler asked groggily before falling unconscious again.

Starscream growled in frustration. The door opened from behind and he looked to see the Vehicon standing on the other side of the door. "Well?" He demanded.

The Vehicon fell down to the floor, revealing Bulkhead with his cannon up. Bulkhead shot the last of the guard before he and Bumblebee jumped into the room with their cannons aiming at Starscream.

In return, Starscream took aim at Fowler. "Not so fast." He felt a tapping on the top of his head and looked up to find Arcee is balancing in the shaft right above him, aiming her gun downward.

"I wouldn't." She threatens.

"Oh, but I might..." Starscream sneered. Everyone is at a standstill, with three Autobots aiming at the smirking Starscream while he aims at Fowler, knowing that the three won't do anything stupid that might harm a human. "Now, Agent Fowler and I will take our leave."

"The emu said... yeah!" Fowler croaked out loud which distracted Starscream.

Bumblebee took the distraction to his advantage and shot Starscream's arm. The Autobots began shooting as well while Starscream dodges all the blast. Knowing that his is pointless, he transform into his jet mode and fled the brig.


"We've got to get this to Optimus." Sam proclaim.

"How do you know it isn't just a recipe for space-nacho?" Miko asked as she slumped her shoulders. "Besides, you said you couldn't even read that thing."

"Yes, but I do know some of these writing."

"Can you... download it?" Jack asked.

"I've got a flash drive." Rafael announced as he dug into his backpack and pulled out his flash drive. "But I don't see anywhere to plug it in. This tech is way alien."

Everyone slowly turn towards the sound of the footsteps to see a Vehicon entering the room. They quickly took shelter under the computer to avoid being spotted. What they didn't know was that Rafael went back to get his forgotten backpack.

The Vehicon heard the ruffling noise and turn to the direction of the noise to see the human. Rafael yelped when the 'Con took aim at him. Sam took action and went to the other direction of the room.

"Hey!" Sam yelled to get the 'Con's attention. He unsheathe his hidden blade from within his jacket sleeve and took a standing position. "Come n' get me." He taunted before he began running away in order to have the 'Con chase him.

The 'Con ignored Rafael and went after Sam. He began shooting at Sam while picking up his pace. He never knew that the boy could run so fast. Sam began dodging each blast while leading him away from his friends. He made a quick u-turn and ran under the 'Con. But Sam wasn't quick on dodging the next attack as one of the blast hit right near him, injuring his right leg.

Sam cried out in pain before falling to the ground. The others gasp at this and Miko covered her eyes with her hands, but opened a small gap in between her fingers to see the action. Jack took action as he ran to Sam and swiftly picked him up bridal style – much to Sam's embarrassment – and carried him behind cover just before the 'Con could grab him. Jack was surprise that Sam is so light-weighted.

"Why do you weight so light?" Jack couldn't help but ask.

"Shut up!" Sam slapped on Jack's shoulder, and then hiding his burning face on Jack's chest.

Jack chuckled at Sam's predicament. "Is that any way for a damsel in distress to talk to their knight in shining armor?"

Sam felt his face burn even more. "Just shut up and let's get out of here!"

Jack agreed before turning to Miko who is still hiding. "Miko, take a picture!"

"Great idea!" Miko jumped in joy before taking out her cellphone and took a picture of Jack, still holding Sam in his arms.

"Not of US!" Sam cried out in dismay.

"Oops, sorry." She apologized before turning her attention to the 'Con. "Hey, you!" She walked out of her hiding space and took a picture of the 'Con.

"Not of that! Of THAT!" Jack pointed at the computer.

"Oh." She said as she realized her mistake and took the correct picture before the Vehicon fired a few rounds and caused an explosion.

Using the smoke to their advantage, the kids leg it from the room, followed by the Decepticon. The Vehicon raised his weapon, ready to strike down the humans, but was interrupted by a loud honk.

Bulkhead transformed into his robot form and tackled and punch the living daylight out of him before transforming back into his vehicle form. At the same time, Arcee and Bumblebee arrived as well. Bumblebee opened his door to let Rafael and Miko in.

"I told you to stay put!" Arcee yelled in frustration as Jack carefully placed Sam on Arcee's seat and Jack climbed on behind him.

"Yeah, well, there has been a change of plans!" Sam remarked.

"A plan that involves you getting injured?" She retorted back.

"Smart, right?" Sam asked jokingly.

Arcee sighed tiredly before they all drove away, escaping the Decepticon warship.

"I like pie. Can we stop for pie?" Fowler asked in daze as he popped up from behind Bee's backseat.

"You found Fowler! ROCK ON!" Miko cheered as Fowler passed out again.


Back at the darken canyon, Optimus and Ratchet are beginning to have a rough time as they continue to cut down the Terrorcons. Optimus and Ratchet stood back-to-back as more Terrorcons began to surround them.

"Optimus," Ratchet called out, getting tired, "This prolonged exposure to Dark Energon... is sapping our strength."

"We cannot falter now." Optimus encouraged.

The two charged again, slicing down the Terrorcons. Eventually, the Terrorcons began piling themselves under Optimus, and then Ratchet.

Megatron laughed as he enjoys his enemies being brought down by his army of the undead. He became a bit amused as Optimus managed to free himself from the pile with both his cannon and his blade. Optimus rushed to aid Ratchet by removing the Terrorcons that were piling up on him.

"After all these years, Optimus... Still at the top of your game." Megatron commented him. He watches as they have defeated their last wave of the undead. "Bravo, Optimus." He applauded for his achievement. "Though this is but a prelude. You may wish to save your strength for the main event."

Optimus withdrew his weapons before he starts climbing up to Megatron. "You will not prevail, Megatron. Not while Energon still flows through my veins."

"Fitting, for it is Dark Energon which flows through mine. And once I'm done with you, Optimus, I'll be taking your pet as my own." Megatron smirked at Optimus.

Optimus knows what he's referring to and he let his anger break loose. No way is he letting Megatron get his dirty hands on his Sam and use him for his twisted pleasure. He attempts to swipe at Megatron, but the 'Con jumped back and transformed into his jet mode and flies off. Ratchet joined Optimus at the top of the cliff as Optimus helped him.

"If this wasn't Megatron's endgame... What is?" Ratchet asked Optimus.


Back at the base, Optimus had welded a metal brace onto Ratchet's injured arm while Sam wrapped his wounded leg with bandages while shirtless, being oblivious to the ogling stares from Jack and Optimus.

"What happened to you guys anyway?" Miko asked with great concern.

"We engaged an army of undead Cybertronian warriors." Ratchet answered.

"Zombies?" Sam and Miko asked in unison. "You fought zombies, and I missed it?" Miko whined as she crossed her arms.

"And speaking of zombies," Ratchet turn his attention to Sam who has just finished taking care of his wounded leg and putting on a shirt, "Sam, I was right about zombies. They can only die if you cut off their limbs. They don't die by shooting them in the head."

Sam glared at the smug look on Ratchet's face before facing in a different direction with a pout on his lips.

"Bulkhead..." Optimus called out. "You exercised extremely poor judgement in allowing the humans to accompany you. And letting Sam get injured in the process."

"It won't happen again, Optimus. I promised."

"But it wasn't Bulkhead's fault." Miko stepped in to defend him. "And check it out. Recon!" Miko flipped her phone with the discovery they found.

Optimus leaned down to get a closer look at the picture. "Ratchet, have look. It could be of importance to Megatron."

Ratchet leaned down was well but was confused at what he saw. "I... don't understand."

Miko lowered down her phone to get a look of it herself. "Oops. That's the 'Con who tried to blow Raf and Sam away. At least, that's what he looked like before Bulkhead rearranged his grill."

"Miko, Raf and Sam was almost killed. This isn't a game! When are you gonna get that through your thick skull!?" Jack snapped at Miko.

"Um... we were all almost killed, Jack. You, me, Raf, Sam... even them!" Miko yelled back.

"Well, if this was just an average day with the Autobots... then I don't want to be a part of it. Not anymore."

This caught everyone by surprise.

"Jack," Optimus spoke softly, "putting you in harm's way was never our intent. However... It is no longer the safety of you three that is at risk... but the safety of all human kind. We will respect your decision if you wish to leave."

The GroundBridge was opened rather quickly after Optimus finished his talk. "No point in long goodbyes. Here's the door." Ratchet said, feeling joy that Jack is leaving. Just two more to go.

Jack sighed before walking down the stairs and head towards the GroundBridge. He stopped when Arcee came up to him. "I know, you don't exist."

"Don't make me hunt you down." Arcee said quietly and sadly as she recalled that part of her memory.

Jack continues to walk through the GroundBridge without looking back. Ratchet closed the bridge once he was sure that Jack made it through. The whole place became quiet until Ratchet decided to break the silence.

"Now then, Miko, can I see that picture that you have?" Ratchet asked eagerly.

"Yeah, sure." Miko gave Sam her cellphone so he can have it uploaded to the large computer.

Once the upload was complete, Ratchet began scanning on the picture. But there was one picture that brighten up his mood. "Well, well, well. What do we have here?"

Everyone went to look at what Ratchet was talking about and saw something completely hilarious.

Sam, on the other hand, was fuming with embarrassment. "Fragging pits of hell!" He curse aloud. "Miko, I thought I told you to delete that photo!"

"You didn't say anything." Miko smiled cheekily. "And besides, you two look make a cute couple." She teased at Sam.

Sam growled before diving into the couch, burying his head under the pillow and trying to mute out all the laughters.

What everyone didn't know was that someone does not like what he was seeing. His Sammy was in the arms of another male. Optimus was glad Jack left the Autobots. There is no way is he letting Jack steal his Sam.


"Please, Lord Megatron, I meant no..." Starscream didn't even finished his sentence as he was slapped by Megatron.

"I ordered you to await my command!" Megatron backhanded Starscream again, sending him flying few feet away. "And instead, your mindless agenda resulted in the disabling of my ship! And the delay of my plans!"

Starscream jumped as he began to crawl away from the approaching leader. "My intentions were pure, Master. I only wanted you to be rid of Optimus."

Megatron slammed his foot on Starscream's head. "NO ONES RIDS ME OF OPTIMUS PRIME BUT ME! DO YOU UNDERSTAND!? DO YOU!?" Megatron yelled out in fury as he added pressure on his foot against Starscream.

Starscream began to choke as he attempts to speak. "Lord Megatron, I will make things right, I swear! I know how to set your plans back on course!"

Megatron released his footing before picking Starscream by the throat. "Explain, Starscream. Quickly."


It was nighttime at Jasper, and Jack is found tweaking something in his bike with the garage door open. He looked up to see a familiar green truck and an asian girl at his driveway.

"Now I understand why you have to rush home." She said sarcastically as she walked inside the garage.

"Don't you have something more exciting to do, Miko?"

"So, this is where you hang, huh?" Miko asked, ignoring Jack's question. "Back home in Tokyo, I have loving parents, and two pure-bred cats, Chi Chi and Ding Dong. I went to the best school, took piano lessons since I was three..."

"How nice of you." Jack sighed, uninterested.

"No, how boring." She corrected. "It wasn't me. Why do you think I jumped at the chance of transfer here?"

Jack scoffed in disbelief. "To Jasper, Nevada. The entertainment capital of the world?"

"Yeah, well, the brochure lied. Piano lessons were starting to look pretty good in fact. But then, the last couple of days happened."

"Do you have a point?" Jack asked impatiently.

"You bet. I saw what you did today. When you tagged along to save me. When you saved Sam with that style." Miko gave a teasing smile.

Jack ignored that last comment before getting up and heading towards his bike. "I've been raised to be responsible. To my school, to my mom, my job, to Sam..."

"Dude, hear me out. You're no fry-cook, you're a rockstar! Stop trying to pretend you're normal, Jack. You'll never fit in. You were born to do so much more. With the rest of us."

"Thanks, Miko, but I think normal suits me fine."

Miko exasperated at Jack before leaving the driveway with Bulkhead. Jack looked back to watch them leave before going back to attach the wheel on his bike.


Ratchet, meanwhile, is checking out the data Miko photographed after poking fun at Optimus over the picture Miko took about Jack carrying Sam like a bride. He finished checking over the data and stare at it in shock. "Optimus!" He called out to him. "These are engineering specs of a space-time vortex generator."

"Megatron is building a SpaceBridge. If he hasn't already." Optimus realized gravely.

"The sooner he leaves, the better." Bulkhead remarked.

"Bulkhead... a SpaceBridge runs in two directions." Optimus informs. "Megatron may not be using it to leave Earth, but to bring through his conquering army."

"The main event Megatron referred to." Ratchet added. "But the only place Megatron could possibly recruit that many fallen warriors..."

"Precisely." Optimus nodded, knowing what Ratchet is mentioning to.

"Cybertron."


I thank you all for waiting while I finish playing my game. You all know how guys are when it comes to video games.

Well, hope you guys like this chapter, and review.
