A/N: New chapter. Featuring Wanda as Ben's caring sister. Enjoy (:


Plumber's Base

Rook, Gwen and Kevin are in here, currently watching Ben with someone talking to Grandpa. For the first time in their life, they finally see the lady Grandpa had been talking about to them.

"So that's Ben's sister?", Kevin said, amazed. "She's hot".

Heard it loud and clear, Gwen struck an elbow at Kevin.

"Ow", Kevin exclaimed.

"I have taken the comprehension that your exact words are she is 'sexually attractive'", Rook said. He learned the meaning of many strange words from Kevin and Ben respectively.

"Not helping bro", Kevin said.

They continued watching Ben and Wanda as the siblings seem to be convincing Grandpa about something.

"Look, Ben, I'm glad your getting a chance to spend quality time with your sister, but Undertown has recently been under attack", Grandpa said.

"Attack? Doesn't surprise me, criminals down there, Grandpa, it's been used as a base for many rogue aliens' operations", Ben said.

"It's different", Grandpa said. "The attack is described by many down there to be something extreme and dangerous. This level of attack may certainly prove this attacker might be too much for the Plumbers to handle. That's why I need you, Gwen, Kevin, and Rook to take it down with any means necessary". He shortly later turns his head to Wanda. "Wanda, I know being with your brother means everything to you".

"I understand loud and clear, Grandpa. Ben is needed. I won't drag him out", Wanda said.

"I'm pleased you understand the situation, but that's not what I meant", Grandpa said before rolling his eyeballs point straight at three people.

Wanda perceived the eye-roll. It's as though Grandpa is guiding her sight to turn where he wants Wanda to look at. As she pursues where Grandpa directed his eyes, she saw Gwen, Kevin and Rook.

"I know you resent Gwen and Kevin. At least cooperate until we know who the attacker in Undertown is", Grandpa said.

"What's wrong with my friends?", Ben asked, confused that Wanda apparently 'resents' his friends.

Sighed, accepting to partake the mission, Wanda turns away from Grandpa. "Nothing", Wanda said with a neutral tone. "Come on, quicker we finish the issue in Undertown, the earlier we leave Bellwood".

Ben glances at his grandad, wondering what sort of thing does his sister have toward them. "Am I missing something?", Ben asked.

"No", Grandpa said assuredly. He moves away.

Ben shortly walks away while pondering Wanda's apparent resentment.


Undertown

Four people in the spacecraft with the little furnace maintaining its levels of calmness without losing temper. The little furnace happening to be Wanda while three in the ship would some times draw glances at Wanda.

Wanda standing in-between Ben and Rook while the latter drives.

Kevin wished he'd use his car, but Grandpa ordered him to stick with the team, much to Kevin's annoyance that they had to be in Rook's ship.

Rook glanced Wanda for a second before looking back at the front. "My name is Rook Blonko", the Revonnahgander introduced. "I'm Ben's-".

"-partner", Wanda said, interrupting Rook. She turned to Rook. "I know. Ben told me a lot about you. You saved him countless times from danger. For that I am thankful. I appreciate you keeping him company".

"You don't have to say it, Miss...", Rook said before struggling to say what Wanda's last name is.

"'Wanda'", Wanda said. "Call me 'Wanda'.

Understanding he can say her name, he says "You don't have to be thankful, Wanda, Ben was the first among his kind I ever made a friend. Well I know he is Anodite, but he is partially of that kind".

"Grandpa has you assigned to be his partner, that's how you two formed a friendship", Wanda said.

"That is correct", Rook said.

Wanda showed a weakly smile before turning her head to the front. "Seems there's so much more to this partnership than I've perceived", Wanda remarked in a positive way.

"Ben is the greatest friend I've met. I owe him my life", Rook said.

"Has he owed you?", Wanda asked as though teasing Ben.

"Resolving my issues with family, helped save Revonnah from the Muroid army, and the Incursean Empire", Rook listed. "I even recall he once saved Rayona".

"That's what friends are for", Ben said.

"You're most certainly right, Ben", Rook agreed.

"We're in accord", Kevin said, popping out over to Ben, Rook and Wanda's portion of the area within the truck.

Kevin's popped-out head alarmed Wanda as she turns around, deathly glaring at Kevin. "I don't believe you understand real friendship, Kevin Ethan Levin", Wanda said in a serious way.

Kevin chuckled in response, thinking Wanda was just playing with him, until he realised she wasn't joking. "It wasn't a joke?", Kevin asked, feeling like this lady is giving him a death glare.

"You tried to kill my little brother many times", Wanda recalled.

Everyone became stunned after Wanda brought up the past involving Kevin.

"The direction of this conversation is going pointless, I've changed, I no longer am the 11-year-old kid with sociopathic tendencies. I would never hurt Ben", Kevin countered.

"Certainly you have changed considerably, but some times you do something that endangers his life", Wanda said. Feeling their arrival is closer, she turns away. "If only Servantis and the Rooters had their brains functioning at weakling capacity".

'If only Servantis and the Rooters had their brains functioning at weakling capacity', this line made Kevin, Gwen, Rook and Ben think what Wanda implies. It seems to indicate Wanda did something to do the Rooters.

"What did you do the Rooters?", Kevin asked curiosly.

"Obviously, I did not kill them. I simply gave them the endless torture they deserved for experimenting on kids, and almost killing my brother", Wanda said.

"At least I'm still alive", Ben said. "Kevin needed to play the villain until he found the right time to betray Servantis".

"But if Kevin was really your enemy, Ben, if he killed you, his treatment would be a lot worse than Servantis", Wanda said. "That's the only reason why I'm not crushing your neck with my hands.".

While he was listening to Wanda's conversation with Kevin, and Ben, he perceived their arrival.

Soon, everyone realised they've arrived, although Wanda prematurely knew it.

Coming out of the truck, Ben's team and his sister saw the location they were told to come to. The house had been scorched as it's distinguished by the charred remains of this house, as well as piles likely ruptured out of the house. There was an attack in here.

"Who could've done this?", Rook said.

"Well whoever attacked didn't want to start a streak on death toll", Gwen said. "Grandpa said the inhabitants made it out alive, though with little concussions".

"Seems witnesses have been exaggerating the attacker", Kevin said.

"Maybe... still, I intend to find out who the attacker is", Ben said before proceeding to head toward the site for a closer inspection.

The team enter the site. Lots of aliens surrounding this site, though barricaded by the presence of Plumbers.

Gwen, Kevin and Rook suddenly notice Wanda's eyes turning brightly red, as well as her body coated in red energy.

"What is she-?"

"Relax, Wanda can detect who the attacker is", Ben said, cut Kevin off from questioning.

Wanda performs a spell, saturating the entire site with red energy.

Ben knows the power of the Force, her Force, can detect who the recent attacker is, and can locate its exact whereabouts.

As soon as Wanda is able to pinpoint where the attacker is, she starts making her red energy trickle, slowly beginning to fade as she no longer requires Force-detection. "She's here", she addressed.

"'She'?", Kevin exclaimed.

Suddenly, something bursts out from the piles. It's a somebody, and its cloaked in brown robes. It surprised Ben, Gwen, Kevin and Rook.

"It's getting away", Kevin said.

"Not if I have anything to say about it", Ben said. He lowered his head to the Omnitrix. He dials a selected alien. He slams the watch, transforming himself into a terracotta and yellow pterosaur-like alien. "Astrodactyl!".

Again he does it: the name-shouting which Ben claims is to strike fear.

Kevin found it less fearful. Even here, it sounds less fearful as the enemy is escaping.

Astrodactyl flies out, chasing after the apparent attacker.

The flyer notices Ben chasing her, prompting her to boost her speed as she tries get far from him. She saw the Omnitrix symbol on Astrodactyl's chest, she knows it's Ben. He won't stop until she's either caught by his grasp, or she decides to stop. She decides the hard way rather than the easy way.

Astrodactyl nearly gets to the flyer's end.

Flyer perceived it. She quickly whirls around, while keeping his movement in the same direction; flying further away from the site, and Ben. She fires a barrage of red beams at Astrodactyl.

One beam almost touched Astrodactyl's left wing. If Ben did not motion a little away from the beam, his left wing would be hit, and it could've resulted him falling, or strongly possible he could be flying at a slower-pace. After dodging several other red beams, in addition to the last one that almost reached his arm, Astrodactyl draws out his energy-lasso, whipping it toward the flyer.

The whip caused the flyer to have a little in bump in its course to escape. As a result, the flyer was a little shaken, and she went a little downward. Despite the stinging sensation, the lady continued flying forward.

Astrodactyl was afterwards forced to race toward her again, though this time he boosts his speed further, while discharging multiple energy breaths at the flyer.

For a moment, the flyer could evade some of the energy blasts, but the next moment changed when she seemed overwhelmed by Astrodactyl swiftly blasting beams in speedy motion. Forced her to fly down to the town. It can possibly avail her if she doesn't get herself slowed down or accidently slam on a building.

Flyer's going down the town. Astrodactyl pursues her through floating down.

The two flyers cross the ones where catering is happening, where the providers are disturbed by Ben and the other flyer crossing above their heads.

The female flyer reaches the structures to leap from wall to wall.

Astrodactyl notices where he is. He crosses through the thin space between two structural buildings, which is where he saw the lady in. He sees her getting away. Astrodactyl flied forward. As he reaches the leaper, and preparing to blast energy from the mouth, he saw from close distance the lady aiming at his yellow beak-like mouth. Ben realised she knew Ben would attempt shooting.

The lady fired a red beam, blasting Astrodactyl away, making the latter fall. With comprehension of Astrodactyl's forceful descend, the lady starts flying out of the structural architectures.

She thought she'd make it out safely, away from danger, away from those that would try to arrest her. She flied very far from the area where she seemingly defeated Astrodactyl. It looks like she can leave. She just needs to get up to the surface. Seconds away from making her reach up to the pipes, the lady is suddenly dragged downwards, as though gravity betrayed her; gravity is pulling her down instead of letting her float upward.

Despite trying her hardest flying upwards, she struggled, and gravity carries on dragging her down. Gravity indeed has been possessed by something with the powers of gravity. Even though she can't force her way out of forced direction, her eyes aren't blocked. She began to realise it's a large, bulky, reddish-brown alien with rocky skin, a giant mouth with teeth that are also made of rocks. It's Ben as Gravattack controlling gravity to manipulate the weight and motion. He's the gravity-possessor that prevented her from escaping.

"What's your hurry?", Gravattack said.

Gravattack may have restrained her movement, the lady wasn't restrained from pulling out a grenade. She pulls it out, readied to toss at Gravattack so he could lose control, and she can escape. As she swings her left arm, a red beam different to her own suddenly hits her face, immediately causing her to lose conscious.

Ben understood her sister arrived, and helped defeat the unknown being. "I did not need help.", Ben said.

The sister smiled. "To be honest, you did.", Wanda said.


Plumbers Base

Apprehension of the unknown female from Undertown forcefully brought her to custody where she is placed in the interrogation room under the watchful eyes of Grandpa, Gwen, Kevin, Rook, Ben and Wanda.

"Is this the lady everyone considers dangerous that it needed the entire team, including the powerful Anodite beside us to take her down?", Ben asked with a slight indignant tone.

The fact they were all brought out just to pursue a flying woman who Ben admitted did force him to put a little more effort, but nonetheless she wasn't worth his problem, Wanda thought.

Ben is annoyed Grandpa would drag them altogether there.

"Before we assert disappointments, shouldn't we take a moment thinking why this became easy?", Gwen suggested. "I have the impression the chase was a setup".

Ben, Rook, Kevin and Grandpa may view it as a possibility.

"Suppose we interrogate the associate", Kevin said, glancing through the glass at the woman sitting silently with collars wrapped securely around her wrists.

Everyone agreed the lady should be interrogated.

"Gwen, you can sense people's aura if you touch the person", Kevin said, recalling the time Gwen touched her in which she sensed somebody Kevin temporarily worked with. "Could you be able to do it?".

"That won't be necessary", Wanda assured them.

Everyone seemed questioning why Wanda would consider unnecessary for them to scan the lady.

"I've already scanned her aura", Wanda said, walking to stand by the glass, watching the lady in the interrogation room.

"Without touching her?", Rook said, feeling surprised. Gwen would require touching someone to collect their memories, according to Gwen herself.

"I've mastered my powers. Reading their auras is like reading a book. Decades of training from the greatest teacher of all time", Wanda reflected.

"If I ask in polite way, who was your teacher?", Rook asked.

Wanda's entire system became frozen as a perpetual state, feeling unable to answer Rook's quesion.

Grandpa appears worried when Rook asked who Wanda's teacher was.

Rook was only asking a question. She shouldn't lash out because of one question. "That's classified", Wanda replied. She half-turned, looking at Rook. "But he was the greatest teacher, the best of us, taught by the best".

Rook took note of it.

Returning to being serious about what they're dealing with, Wanda looks at Grandpa. "Charmcaster", Wanda addressed.

This brought-up name has admittedly been a shock for everyone. What would Charmcaster want from Undertown?

"Forgive me for stating it in the opposing way, it seems uncharacteristic Charmcaster would attack a subterranean city", Rook said.

"I'm taking his point", Kevin said, agreeing with Rook. "The only two people she's fixated on is her uncle and Gwen".

"She has attacked a town, has she not?", Wanda asked, looking at Gwen and Grandpa. "Luring Ben, attempted to switch bodies with him, tried the murder the family multiple times.".

"Wanda has a point", Grandpa said. "Whatever her motives are, Charmcaster is cruel, willing to commit sinful acts in exchange for her personal gains".

"We can manage", Gwen said, giving some assurance to Ben and Wanda. She looked at her two cousins. "I'm sure you two need a quality time to spend".

"Gwen-"

"No, Ben. I can deal with Charmcaster", Gwen cuts his cousin off. "It isn't the first time I fought her, remember?".

Knowing Gwen's many encounters with Charmcaster, Ben didn't have anything to counter to convince Gwen she shouldn't push him away from helping the team defeat Charmcaster. Gwen has proven to be capable of defeating Charmcaster many times.

"Have fun", Gwen said, smiling at Ben.

He's doubtful, but assured. Charmcaster isn't the greatest threat to the planet. Nothing will go wrong by the time Ben returns Bellwood.

Seeing that the team doesn't need her and Ben's help, Wanda uses her powers, teleporting herself and Ben out of Bellwood.


Away from Bellwood...

Teleported out of Bellwood was one notice, being in something comprised of green and black was another that Ben almost did not know where was until he realised he was facing the seat. His position of sitting is the opposite. He rotates his opposite position around, now sighting the highway. He realised they're actually in the car, and it's not just any ordinary vehicle. "Hey!", Ben exclaimed in surprise. It's his sport car. "The DX Mark 10. Thought some joyrider stole it before acquiring the Tenn-Speed".

"I 'borrowed' it", Wanda claimed.

"'Borrowed it'? Sounds more to me you used it", Ben said in a serious way.

"Hey, the kids needed to be in school", Wanda countered.

"Still, it doesn't justify-", Ben suddenly paused speaking after processing over hearing the one word mentioned by Wanda. "Sorry, did you say 'Kids'?".

"Rats, why did I say 'Kids'?", Wanda exclaimed as she ruined the surprise.

"You have kids?!", Ben exclaimed in extreme shock, goggling at his sister. He turns his eyes away from Wanda, thinking about the meaning of this revelation. "That would mean I'm... the uncle, their uncle". He's freaked out. A 16-year-old is an uncle. Uncle Ben, he thought.

"No you will pretend to forget what I just said, and take us to Westview. And until we reach there, no comment whatsoever about...", Wanda said, before struggling to utter. "...that".

Ben scoffs before saying "Yes ma'am". He subsequently starts the DX Mark 10, launching the sports car along the straight, empty lane.


Bellwood

Rook, Gwen and Kevin are on their way back to the Proto-TRUK.

"I'm aware you and Charmcaster have history, may I ask why we're not taking Ben and Wanda with us?", Rook asked.

"Because I don't trust Wanda", Gwen answered.

Kevin and Rook looked at Gwen in astonishment, eager to know why she doesn't trust Wanda.

"She's hiding something", Gwen said.

The trio are almost arriving at the Proto-TRUK.

"Yesterday, Wanda arrives in Bellwood, reuniting with Ben. That very same day, an attack in Undertown happens. Witnesses claim they saw red light then they blacked out. Wanda generates red energy. Think it's a coincidence, two things happening in the same day?", Gwen said.

"I respect your judgement, but after learning much from the Magister regarding Wanda's caretaking of Ben, I find it absurd she'd be a bad person", Rook said.

"We've encountered people, once good, turn bad", Gwen said sadly.

"So your plan is to spy on Wanda?", Rook surmised.

"No. We'll pursue the 'suspect', before we confront Wanda.", Gwen said, referring to going after Charmcaster first even though she has the impression Wanda is implied to have been discreetly involved yesterday's event. "She mentioned Charmcaster, so maybe Charmcaster might give some understanding who Wanda really is.".

"Could've informed Ben your suspicions of Wanda", Rook said.

"No. Wanda would know. They have a connection through the Force. Their relationship stemmed from the day Ben was under Wanda's arms", Gwen explained.

"Eventually, you will have to tell him", Kevin said, taking it from experience that such secrets kept from someone can lead to consequences, bad results. "Even if it's hard for him to acknowledge the truth.".

Gwen did not want to hurt Ben. She never intended to hurt her own cousin. She wants Ben to be happy, which is part of the reason why she pushes Ben to be with Julie. Now that Wanda's with him, and Ben seems very happy as though all that low energy bar transcended to intense levels higher, Gwen appears hesitant as it would damage his happiness, and potentially sabotage Ben's relationship with Gwen.


Elsewhere in the world...

DX Mark 10 is fast, yet limits are existent. No matter how great the tool is, the tool has a limited capacity, same way his Omnitrix has a limited capacity in terms of time. As a matter-of-fact, Omnitrix just needs to recharge before it can be used again. Unfortunately that is not the case for the sports car. The moment it slowed down is when it became true the car is losing charge, and there's no way to charge it because it needs a charging station.

"We're stuck", Ben said, referring to not being able to move with the DX Mark 10. If they didn't use the sports car, they would easily fly all the way to Westview.

"Wouldn't hurt to use the Omnitrix to charge your car, would it?", Wanda said mildly, resting her elbow on the car seat.

"I know I use my Omnitrix most of the time to make my life easier, but it's my sports car. What if my aliens inadvertently damage the battery? Shocksquatch, Buzzshock, Frankenstrike, Ampfibian. Insurance isn't so cheap, you know."

"Do you have a better idea, little brother?", Wanda said softly.

Ben is reluctant to attempt it. Car is quite expensive for a teenager. He could cause the entire car to explode. Nevertheless, Ben gets out of the car.

Wanda saw a burst of green light, meaning Ben has transformed.

"Feedback", Ben shouted his alien name after turning into his selected form. He thrusts his antennae into the hole, in the process, he transfers electricity from his tank into the sports car, charging it. This will take a while. He might as well get comfortable knowing he's sapping energy off from his body.

Since Ben is preoccupied charging, Wanda takes a moment to hone her sixth sense focused on Bellwood. She senses Gwen, Kevin and Rook's conversation, and it dissatisfies her. But it does appear not all is seen bad. There's a chance they may never know what she's done.

Suddenly, a green beam exploded, causing Wanda to realise Ben is finished charging the car. She sees her brother entering the car, preparing to start the vehicle.

"All done", Ben said. He then noticed Wanda is a little unhappy. "Disappointed?".

Wanda immediately snapped, quickly shaping her face into a happy expression. "Why would I be?", Wanda said rhetorically. She quickly turns the focus on travelling to Westview with saying "We haven't even reached a hundred miles. Hurry up".

DX Mark 10 finally drives forward, resuming the course to Westview.


A/N: There is a little conflict between Wanda and Kevin Ethan Levin, which you might've noticed. Wanda dislikes Kevin. How will they get on friendly terms?
