The bigger they are, the harder they fall, Supergirl thought as she watched the latest alien plummet to the earth after she dealt the final knockout blow. This one had been tough, sort of, another K'hund that had been in Fort Rozz was finally on his way to the holding cells at the DEO. The thing was, she didn't want the fight to stop. She'd been spoiling for a good fight all day and even after defeating this alien Supergirl still felt like she had some pent up aggression she needed to release.

"Supergirl, you ok?" Alex called to her over the earpiece. "Yeah," Supergirl replied, "Piece of cake." "Good, we've got him in custody and will meet you at the DEO," Alex replied before signing off. Yippie, now I get to go and answer a bunch of questions from Hank about why it took me so long to defeat the alien. Nothing I ever do is good enough. So I took my time kicking his alien ass, at least I got the job done.

Hank Henshaw walked up to Supergirl as she entered the DEO control room, "So, you want to tell me what that was all about? He wasn't even close to you in power, speed and ability and yet it took you nearly 30 minutes to defeat him. Care to explain what happened?"

Supergirl just looked at the director with a blank stare on her face, "What's the big deal with how long it took me to beat him? I did it, he's in custody, no one got harmed. Sorry it wasn't to your satisfaction, SIR!" She said the last part with such resentment sarcasm that it caused Hank and Alex to look at her with some confusion.

"Supergirl," Alex began, "You okay? Hank's just concerned because it shouldn't have taken you nearly that long to defeat a K'hund, and quite frankly I'm concerned too. The last time you were like this you were under the influence of the red kryptonite, what's going on?"

Supergirl put her hands on the table console in the centre of the room, "Look, I've just got a lot on my mind right now, and needed to vent out a little frustration is all. I figured you wouldn't mind me taking it out on an alien, I didn't hurt him or anything, I just took my time."

"What's going on that you needed to "vent" on an alien?" Alex asked, looking at her sister with concern written all over her face. "I'd really rather not talk about it, Alex." Kara replied. Alex just watched the face of her sweet sister turn from anger to hurt to sadness in swift succession.

"Well, just to be sure you're ok," Hank began, "you're going to see Dr. Hamilton for some tests and then spend at least 30 minutes training with Alex." Seeing Supergirl about to object, Hank continued, "No argument, just do as you're ordered please."

Supergirl turned on her heels and headed to the medical bay to see Dr. Hamilton as ordered. "Hey there," the doc smiled as she looked up from her microscope to see Supergirl standing in the doorway, "you doing ok?" Sighing heavily Kara entered the med bay, "The director wants you to run some tests on me to make sure I'm okay because I took too long to bring in an alien." Dr. Hamilton stood up, "I see, were you hurt in the encounter?" "No," Kara replied taking a seat on the gurney, "I just took my sweet time kicking the ass of the much weaker alien and now Henshaw's all worried as to why."

Dr. Hamilton smiled at the young hero as she took a stool in front of Kara, "Okay, want to tell me about it?" "Not really," Kara replied, "can we just get this over with, I have something I have to do tonight and I don't want to be late because I'm stuck here doing some stupid tests." So the doc got right to work on the various tests she'd run a dozen times on Kara after a mission to ensure she was okay.

"She's fine, physically," Dr. Hamilton spoke to Director Henshaw, "but she seems sad or even depressed to me about something." Hank nodded, "Thank you doctor." Supergirl and Alex were already well underway in their training session.

"Again!" Supergirl ordered her sister. Alex could see the anger and the frustration about something in Kara's eyes and she knew one of the best ways to get it out of her was to practically beat it out. Fists up, ready to block and counter punch any attack by Kara, they slowly circled each other on the fighting platform. The kryptonite emitters were on, but not on high enough to hurt Kara, just to make sure she couldn't hurt Alex accidentally.

Lunging forward Kara swung her right fist at Alex's face, only to find it met with an effective upper block, followed by a powerful counter punch to Kara's stomach, then an upper cut to her chin. Kara flew backwards onto her back, stunned at the speed and power her sister was using on her.

"Didn't know you had that in you," Kara quipped as she got to her feet and readied her stance again. "Bring it on, sister!" Kara yelled at Alex, using her hands to egg Alex to step forward for another round. Alex didn't say a word as she raised her fists and circled Kara again. The look of anger in Kara's eyes nearly broke Alex' heart and for a brief moment caused her to hesitate. Kara seized the opportunity and lunged at Alex, dropping down and sweeping Alex's legs out from underneath her. Alex landed on the platform with a thud, and barely had enough time to put up an arm to block the punch Kara was dropping down to her face as she straddled her.

Alex grabbed the arm and using good technique, speed and strength, she turned Kara over onto her back and got on top of her, raising her arm up to deliver a nasty blow to her face, when Alex stopped herself and got off of Kara. "What?" Kara demanded when she stood up. "Too afraid to finish the job?" "What is going on with you Kara?" Alex looked at her sister with confusion on her face. "I'm sorry," Kara replied, "I guess the whole petition thing has me on edge a bit, I'm sorry."

Alex helped Kara to her feet and wrapping her arms around her gave her a giant hug, "It's ok, I get your frustration. Don't let the few who don't know who you really are and what you've done for the City not to mention the entire planet get you down. I'm here for you no matter what, if you ever need to talk, ok? So,potstickers, ice cream and cuddling tonight at your place…you're buying!" Kara smiled at Alex, "Deal and a date! Sorry, but I gotta go, I've got a meeting with Cat Grant. See you later…love you!" And with that Kara was gone from the DEO heading home to meet with Cat.
