Dr. K was sitting in her lab looking over her research results. So far, it seemed like love was something that made people happy.

Take Flynn and Hayden for example. Dr. K went to their file. Flynn and Hayden were always happy and joking around with each other.

If one were to look at Dillon and Summer, one would see that Summer always finds a way to brighten up Dillon's day. She definitely lived up to her name.

Scott and Sam were happy together as well. They seemed to understand each other on a level no one else did.

And finally, Dani and Greg. Dr. K spend a lot of time researching them, not only because Greg was one of her best friends and she could get close to him without, but because their relationship was very similar to the one Dr. K believed she would be in with Ziggy. And she realised, if those two can make it and be happy, then there was a chance that she would be with Ziggy.

Dr. K's paperwork was complete and Dr. K was no longer intimidated by letting her emotions free. If she was right, which she always seemed to be, love wasn't going to hurt her.

It was time to do some field work.

-----RPM-----

Ziggy and Hayden were sitting on the couch, backwards, because they were just that bored.

They were also discussing powers. Because Ziggy didn't have any, he thought it would be cool if he could fly, or turn invisible, or heal.

"So, aside from the blood loss thing, is it impossible for you to die?" he asked. Hayden shook her head.

"Well, if I were to lose my powers and get hurt, I could die," Hayden shrugged, "And, this hasn't been proven or anything, and it's just my belief, but I think if I were to get sick with an incurable virus or disease, it could kill me."

Ziggy sat up and looked over at the young girl, "How? I though your body would just heal it?"

Hayden laughed, "I said it was incurable, Zigster. There are some diseases that the body just can't seem to cure on its own, and needs medicine for a little help. But I think that if I do catch something that a regular body can't cure, mine won't be able to either."

"Why?"

"Because my body heals like you guys, just really, really fast. So if there's something out there that the human body and medicine can't cure, I think I'm just as vulnerable to it as you guys."

"So, you're not indestructible?"

"Sadly, no. But I don't think there's anything out there the body can't handle, so in a way, I am invincible."

"Sweet!" Ziggy smiled.

Dr. K stepped in the room, putting the clipboard in her hands down. She walked over to Ziggy and Hayden.

"Hayden and Ziggy, you two are upside down?" she asked them.

"Yep," Hayden nodded.

"We're bored, Doc," Ziggy smiled.

"Is this some kind of special brain exercise that will aid you in battle?" Dr. K asked.

"Nope," Hayden said.

"We're just bored, Doc," Ziggy repeated.

"I see... anyways, if it's no trouble I would like to speak with you, Ziggy," Dr. K said. This made Ziggy turn around and sit up straight. Hayden did as well, only because last time Dr. K asked to speak with Ziggy, it was entertaining.

"Shoot, Doc. I'm ready to hear anything and everything you have to say to me!" Ziggy smiled.

"I will start with a compliment," Dr. K stated, "Ziggy, you look very handsome today."

"Whoa," Ziggy frowned, a little surprised those words came out of the small doctor's mouth. She never complimented him. Now she was doing it freely. Was there a gun aimed at her or something? "Wow, thank you Dr. K... you know, I did shower this morning and I feel good!"

"No wonder you don't stink," Hayden giggled.

"So, what else would you like to tell me?" Ziggy asked.

Dr. K took a breath and prepared herself.

Suddenly, the doors to the garage flew open as four teenagers walked in. All wore angry expressions on their faces.

Hayden's expression seemed to sour as soon as she locked eyes with the boy on the far right. They were caught in an angry staring contest, with neither backing down.

The only difference Dr. K and Ziggy spotted between the two, was that Hayden's anger was trying to make the tears forming in her eyes.

"Hayden, so good to see you again," the boy in the middle laughed.

"Alex," Hayden growled, never taking her eyes of the boy with brown hair.

Ziggy leaned over, tapping Hayden on the shoulder.

"Um, you know these guys?" he asked.

"Unfortunately," Hayden growled.

Summer walked into the garage with Dillon after picking up groceries and she spotted the four teenagers. Her expression dropped as she dropped her bags and she ran over to Hayden, putting her young cousin behind her protectively.

"Get the fuck out of the Ranger base," she growled to the teens.

Alex laughed, looking at the others, "Did you guys hear that?" he asked. "She thinks we're going to listen to her."

"We're just here as a warning," the boy on the right smirked. The girl nodded.

"Yep," she smiled. "You guys are going to pay for ratting us out."

"We didn't rat you out," Summer frowned. Her hand was placed on Hayden's arm, and held it tight to comfort her. Everyone could see she was feeling a little uneasy. "You guys failed for rule violations and for being jackasses!"

"We wouldn't have failed for rule violations if little Hayden over here didn't call us out in the middle of a challenge," the girl grinned, pointing to Hayden. Summer got a sick feeling in her stomach as she watched the smiles on the four teens' faces. She knew they were up to something.

It had been a little under a year now since Mike, Hayden and Summer were chosen for RPM and since they had distanced themselves from their rivals. What was dangerous about that was the fact that they parted on bad terms.

Parting on bad terms meant that this situation was going to happen sooner or later. Of course the rivals were going to want revenge. It was a really dangerous deal, especially seeing as they knew the Rangers so well now. They knew their powers well, and a year to study them meant they could have found weaknesses.

Summer didn't want to risk it. She kept Hayden behind her as she glared at the rivals.

"Get out of our base," she said.

"We'll get out when we damn well please!" the boy on the right smirked. Dillon walked up behind the group, standing over all of them with a look that told them he wasn't happy.

"My girlfriend told you leave. I suggest you do before Kaylee starts obsessing over a new kind of sandwich."

"Which kind?" Alex asked, being the only one to step up to Dillon.

"Knuckle," Dillon smirked before his fist met Alex's face. Alex fell to the ground, holding his jaw while the others helped him up.

"The dude's insane!" the boy on the left frowned before running out.

Hayden stepped out from behind Summer, "Yeah, and he's not even angry yet!"

"Oh, now you speak up," Summer laughed.

"Um," Ziggy started, reminding Summer and Hayden that he was present and he had seen the whole thing, "Who were they?"

"The kid got blood on my hand," Dillon frowned, looking at his fist. Summer patted Dillon's shoulder with mock sympathy and watched as Hayden explained to Ziggy and Dr. K who the four teens were.

"The guy Pickle punched was Alex," she said, "The guy on the left was Nathan... my ex-boyfriend."

Flynn had somehow wormed his way into the room to hear that and was in shock.

"Did I hear something about an ex?" he asked.

"Those kids were the four kids my mom and Aunt Kira put us against in the test for the Ranger suits. They were caught cheating and breaking the rules and causing bodily harm so mom kicked them out," Hayden explained.

"I'm guessing by your intense staring contest you and Nathan aren't the best of friends?" Ziggy frowned.

"He said he loved me but he was just another huge jackass who broke my heart," Hayden lowered her head, remembering that day clearly. Nathan had been the first boy that Hayden fell for, hard, and in the end, it seemed he would rather cheat and wear the Ranger suit than be with her.

Dr. K saw the tears as Hayden continued to explain to Ziggy, Dillon and Flynn how Nathan, Alex and the other two rivals lost their position on the team. The more Hayden spoke about Nathan, the more hate Dr. K saw in her eyes.

At the same time, Dr. K saw pain. There were still some scars left from the broken heart Hayden had suffered.

Maybe love wasn't all fun and games. Maybe Dr. K was taking too big of a risk. After all, she knew there was only one person out there for everyone. Chances were she wouldn't find him right off the bat.

What if her heart was broken again? Dr. K knew she couldn't deal with the pain again.

She slowly slipped away from the Rangers as the others assembled. She was going to have to do more research on love to figure out if it was worth it.

-----RPM-----

With her clipboard in hand, Dr. K walked to Kaylee's bedroom. She knocked on the open door and stepped inside.

"Come in?" Kaylee laughed. Dr. K took a spot beside her on the bed.

"I would like some help," she stated.

"Okay... wow... um... help with what?"

"Love."

"Hello!" Kaylee frowned, moving away from Dr. K and jumping off the bed. "I really don't feel like having that talk again."

"I don't need the talk," Dr. K sighed, rolling her eyes. "I need to know if love is worth it."

"Worth it? What do you mean by that?" Kaylee asked.

"I mean... I don't know. I was hoping you would have some answers," Dr. K looked up at Kaylee. Kaylee pulled away.

"Whoa... um... it is?"

"It is what, Kaylee?"

"It's worth it?" Kaylee suggested.

"How?"

"How? Um... well, when you find the one person who..."

"Is there any way to find him without the heartbreak?"

"Oh, okay now I know where this is going," Kaylee smiled. She sat back down with Dr. K and wrapped her arm around her. "Alright, K, listen up. The heartbreak is a part of the deal. Without it you wouldn't know what you want. When it happens, you are broken, devastated and totally lost and confused. But if it never happened, you would be stuck in a relationship you would regret. You wouldn't know what you want in a partner and you would never be happy."

"Please explain."

"I just did!" Kaylee groaned. "Look, when it comes to love, you have to take the good with the bad. There are no skipping steps or counting cards. All you have to do is put yourself out there."

"But I don't want to get hurt," Dr. K admitted. Kaylee squeezed her gently.

"It's a good kind of hurt, K," Kaylee smiled. "It's a hurt that'll make you grow. And if you do get hurt, it's not the end of the world. There is always going to be someone by your side who's going to help you through it all."

"Who?"

"Friends? Family. People who already love you, and who always will."

"Are you sure it's worth it?" Dr. K asked.

"Absolutely," Kaylee nodded with a huge grin. "I wouldn't tell you otherwise, Doc, and I wouldn't let anything keep you from being who you are. If you let things happen, you'll find life is a lot easier."

"Thank you, Kaylee," Dr. K said, taking her clipboard. "Some more research is still required, but you did help further it."

Kaylee laughed and smiled, "Anytime doc! Oh, and when you go talk to Ziggy, tell him he owes me ten bucks!"

Dr. K turned around with a shocked expression. She tried to recompose herself quickly and steer Kaylee in the wrong direction, "It is in no way Ziggy the man that I'm..."

"Please, Dr. K, I'm a mom, I know these things."

"You're not my mom."

"After this talk, I might as well be," Kaylee grinned. "Don't worry, I won't tell him."

Dr. K smiled and turned to walk away.

"But he still owes me ten bucks!" Kaylee called after her.

-----RPM-----

Meanwhile, Hayden was in the park with Mike, Summer and Flynn, beating up a poor punching bag that never stood a chance as she thought of Nathan's return.

"He was such a jerk!" she screamed, beating another hole into the bag.

"Take it easy, Hay," Mike frowned. "Save it for the fight."

"Fucking son of a bitch really thinks he can mess with me?" Hayden frowned, hitting the bag and making the hole bigger. "I'm in-fucking-vincible!"

Around the corner, Chloe was watching closing as she snuck up to the group. They never detected her as she unscrewed the top to the pink water bottle (the bottle that should have been hers), and poured some powder inside. She shook it, mixing the powder with the water, before sneaking away.

"Him, and his stupid sister and cousins are the most despicable human beings on this planet!" Hayden yelled. "Billions of people died at the end of the world, and they couldn't be included in that?"

"That's a little rough, don't you think?" Summer frowned. "I mean, he broke your heart. He deserves to be buried to his neck and left to rot. But to want him dead...?"

"I don't know," Flynn said, cracking his knuckles. "I really don't like the kid."

"Of course not," Mike frowned. "He broke Hayden's heart. But he doesn't deserve to die with the rest of the world's population."

"Thank you," Summer breathed.

"He deserves to be captured by Venjix and forced to work alone in a prison camp where he'll suffer for the rest of his natural life. Then, when death comes, he gets implants to keep him going and he's forced to life the rest of time as a slave to Venjix."

"I take it we really, really hate this guy," Summer sighed. Hayden hit the punching bag again, and her hand disappeared inside it. She kicked her foot up, pulling her hand out and flipping the bag over her head.

When it landed on the ground, it was no longer a bag. It was now a piece of fabric ripped apart by hate.

"Just a little," Hayden sneered. She wiped her brow and picked up her water bottle. The boys and Summer watched as she finished it, barely taking the time to breath.

"Don't choke," Flynn laughed.

"Its water," Hayden gargled through the water that hadn't gone down yet, causing some of it to overflow in her mouth and spill all over. She wiped her mouth and sighed.

"Look, guys, we're Rangers now. We can take whatever they throw at us," Summer smiled, taking the bottle from her cousin and stuffing it in her bag. "We're worrying about nothing. After all, they threatened revenge on Hayden. What are they going to do to her? She's invincible, remember?"

As Summer slung the backpack over her shoulder, the boys laughed. She was right.

"How about we go home and relax?" Mike suggested.

Flynn and Summer nodded. Hayden nodded as well, bending over to pick up the remains of the punching bag. Corinth had a strict rule on littering.

As she came back up, her vision blurred until all she saw was dark. She swayed slightly and nearly lost her footing. Thankfully, Flynn grabbed her arm to steady her.

"Whoa, lass," he said.

"Walk much?" Summer teased.

Hayden stood still for a moment as the black disappeared and her vision returned.

"I'm okay... I think I just caught mom's dizzy spells."

"You don't catch dizziness," Mike frowned. "Actually, you don't catch anything. And if you do, you're body just heals it."

"Except when it comes to missing school," Summer teased.

"I'm sure it's nothing then," Hayden smiled.

"Positive, Hay?" Summer asked. Hayden nodded but had to stop. Any kind of movement caused her to become very dizzy. Now, because of it, she felt weak. Standing was proving to be a challenge.

She didn't want to worry her cousins though. After all, she had just spent the last hour working out, without a break. Her body was probably just begging to take a break.

"Yeah, it'll pass," Hayden smiled. She jumped up on Flynn's back, thinking a ride back to the garage would give her some rest. "Onwards to the castle!"
