Kayla had been working with the team for almost a month now and had surprisingly fit in very well. Skye, of course, was thrilled that her friend was now with them, especially since Ward and May had been giving her a cold shoulder since the Miles incident. FitzSimmons quickly warmed to her, and found her mere existence incredible. Coulson was happy that Skye was much more comfortable and thought that Kayla was being a good influence. Surprisingly, May even seemed to have a soft spot for her and gave her encouragement and compliments whenever she saw the girl training. And Ward? Well Ward had changed since Kayla showed up, the whole team could see it. He was less closed off than before, and they even caught him with a smile on his face once in a while. Ward knew it could be a problem that the girl was getting under his skin, but he just couldn't help it. They trained constantly, even though Kayla was already good at fighting. She had the techniques down, but what she was really lacking was strength. She was barely 5'5 and only 19, so lacked a lot of muscle which worried Ward. That's why Coulson had instructed him to help her train her telekinesis abilities as well.

"Ugh, this is useless" Kayla sighed.

"No, it's not. Try again" Ward told her.

Kayla tried staring harder at the pen she had been trying to move for ten minutes, but it was no good.

"I give up" Kayla mumbled.

"Try again" Ward insisted.

"Why? It's never going to work" Kayla stated, standing up.

"You don't know that. Try it again" Ward retorted.

"No!" Kayla shouted, and suddenly the pen flung off the table and hit Ward in the chest.

"I told you so" Ward smirked, triumphantly.

"Pft, I don't really think having anger as a trigger is going to work very well" Kayla explained.

"Well then we'll figure out a better trigger" Ward told her.

"I hope so" Kayla sighed.

"You did good" Ward insisted.

"Thanks but…ow…" Kayla trailed off, as she suddenly placed a hand on her head, wincing.

"Hey, what's wrong?" Ward questioned.

"Apart from the agonizing pain?" Kayla mumbled, as Ward led her to a seat.

The pain slowly started to fade but Ward was still concerned.

"C'mon, I'm taking you to FitzSimmons. Can you walk?" Ward asked her, as he helped her up.

"I don't think so" She said, dazed.

"Alright then" Ward replied, as he placed a hand on the back of her thighs and picked her up bridal style.

"Hey! What're you doing?" Kayla cried.

"Taking you to them, just relax, okay?" Ward explained.

"Okay" Kayla mumbled, as she rested her head onto Ward's shoulder, suddenly very tired.

Ward quickly got her to the lab where FitzSimmons were arguing about a new weapon, but instantly stopped when they saw Ward and Kayla.

"What happened?" Jemma asked, worried.

"We were trying to train her telekinesis, and then she got mad at me and it actually worked. She managed to throw a pen at me!...But then she got this pain in her head…" Ward trailed off, as he carefully laid her down on a table.

"Its fine, really. It doesn't even hurt anymore" Kayla told them.

"Even so, we should run some tests" Fitz insisted.

"Let me guess? Needles" Kayla questioned.

"Sorry" Jemma grimaced, as Kayla sighed.

FitzSimmons soon ran there tests as Kayla rested up. After an hour they suggested that she should be alright to walk around the plane, but shouldn't have to train for the rest of the day.

"I'm sorry" Ward told her, as he helped her off the table.

"Guilt's an emotion you know, Tin Man" Kayla joked.

"Kayla, seriously. I'm sorry, I shouldn't have pushed you" Ward exclaimed.

"Well I shouldn't have got angry. So, it's both of our faults and we're both idiots, how about that?" Kayla explained.

"Sounds good" Ward said with a slight smile.

"Kayla! Oh my God, are you okay?" Skye asked, as she ran into the room and hugged her friend.

"Yeah, I'm fine. Nothing serious" Kayla shrugged.

"Really, cause you don't look so good" Skye told her.

"Hey!" Kayla said, nudging her shoulder.

"It's rather strange why your powers caused you pain...does it hurt a lot when you injury yourself?" Simmons questioned.

She was trying to figure out why Kayla using her powers caused her pain, and Skye and Ward also were interested to hear what her theories were.

"Yeah, but injuries hurt everyone" Kayla shrugged.

"Hm..." Simmons frowned.

"What?" Kayla asked.

"Can you give me your hand?" Simmons inquired, as Kayla instantly did so.

Simmons then picked up a monitor and placed it on Kayla's wrist and then used a scalpel to cut down the girl's palm.

"Ow! What was that for?!" Kayla exclaimed.

"Just as I expected" Simmons said triumphantly as she looked at the monitor.

"What is?" Skye asked.

"When Kayla uses her powers she experiences a certain amount of pain, so when she heals it hurts more than it would hurt us. For example me cutting her hand hurts her more than if I'd cut my hand" Simmons explained.

"Yeah, but I remember when Kayla would get hurt in the past and she never kicked up more of a fuss than other people...maybe less even" Skye insisted.

"That's because she has managed to create a high pain threshold" Simmons told them.

"So every time she uses her powers she'll be in pain?" Skye asked.

"Theoretically, although if she practises her powers a lot she may be able to-" Simmons was cut off by Ward.

"No, if it hurts her we don't do it!" Ward exclaimed.

All three women raised their eyebrows, in surprise.

"What? I'm just saying" Ward said, shrugging.
