Author's note: Hello all! Here's the next chapter, I have more of a plan for the plot going forwards with this story now :) Hope you all enjoy, and as always thank you so much for all the follows, faves and reviews! They really make my day when I see how much people like what I write :)


Maggie was still standing in the central office of the DEO, watching as an extremely worried Alex guided Supergirl carefully to a bed and then proceeded to move quickly but efficiently around the room, switching on the lamps that would swiftly recharge the superhero.

She switched on a computer and began typing away, she turned and spoke with Supergirl but Maggie couldn't hear the words. She moved closer and watched as they chuckled over a shared joke, there was obviously some history between them; they obviously cared for one another…

She sidled up to the doorway and leaned on the edge, her arms crossed, watching the two women interact and studying their behaviour towards one another.

"I'm hungry…" Supergirl mentioned as she lay prone on her back, soaking up the sunlight with her hands behind her head and her eyes closed.

"You're always hungry!" Alex chuckled, sounding calmer now that Supergirl was recovering, she didn't make any move from the monitor, just continued to tap away, analysing Supergirl's biometrics. Neither of the women had noticed Detective Sawyer watching from the doorway.

"Soooo… how did it go with Maggie?" Supergirl asked excitedly, the lamps already doing their job at bringing the super woman back to her usual perky self.

"It was amazing…!" Alex began, she turned towards the bed "She is just so…" Her eyes turned a little dreamy as she thought of their date and subsequent night together.

"Ahem…" Maggie coughed, still holding the doorway up.

"Oh! Hey babe!" Alex exclaimed, turning as she heard the other woman's not so subtle cough.

Supergirl sat up suddenly; still not used to missing her powers, especially her super hearing (and she hated it when people snuck up on her).

"Oh hi Detective Sawyer…" She mumbled as one hand drifted up to her face to unconsciously push glasses that weren't there further up her nose.

And everything suddenly clicked for Maggie, all of the times she had seen Supergirl fiercely defending Alex in addition to being on the agent's speed-dial... Of Kara's overprotectiveness towards Alex and her absolutely ridiculous excuses…

Supergirl was Kara Danvers!

"Ohhh…" Maggie muttered under her breath, mentally slapping her forehead at how she had been so worried about another woman being too close to Alex, that she had completely missed the obvious answer staring her in the face (now quite literally) "Supergirl's your sister..!"

"What, what are you talking about? My sister…?"

"Whut…?! Who's Ka...ra…? I don't know any Kara… I mean sister! Whose sister!? Not mine…"

Both the Danvers sisters spoke at the same time, Kara's eyes shifting frantically from side to side as if looking for a way to escape.

"Come on…" Maggie replied, walking further into the room. "Look, look Alex, I know you… The only person you get that torn up and worried over is Kara… Plus, the glasses don't help" She grinned at Kara "Nor the urban climbing excuses…" Her tongue poked out of the corner of her mouth as she teased the superhero.

"I always said that too… it is kind of ridiculous that no one else has figured you out yet…" Alex turned to Kara with a smile and a chuckle.

"Wait what!? Aleeeex…" Kara whined as the two women both grinned at her.

"Sorry sis" Alex shrugged "I've said before that we needed to work on your undercover skills…"

"Fine…" Kara sighed "I'm still hungry though…" She looked back up at the brunettes with a puppy dog expression.

"Alright, alright!" Alex held her hands up defensively, "Don't let it be said that I stand in the way of Supergirl and food" She turned to Maggie "Do you wanna come with?"

"Sure" Maggie replied smiling and followed Alex out of the room.

"Don't forget the potstickers!" Kara called out after them before flopping back down onto the bed and getting comfortable under the warm bright lights again. She told herself she would worry about her disguise another day.

Before leaving, the two brunettes checked in with Hank. He was leaning over Winn's screen looking at what his newest agent was showing him.

"I've been looking for a way to track it and I think I've found something…" Winn pointed to a section of the map on his screen. "So here, here and here are where it's been sighted, this one is from this morning where Supergirl fought him and has the strongest signal..."

"Signal?" Hank questioned.

"It's a type of radiation I've not seen before which is why we never picked it up with the usual scans. I only noticed it when I was looking for anything in common with the places he's hit. I recalibrated the sensors to cover a wider spectrum and picked up this."

Winn hit a combination of keys on his keyboard and the map lit up at all three places, the signal obviously weaker in the older spots. Interestingly though, the lit up areas could be traced away from the known locations for a short distance.

"So this is where he was seen retreating, Winn pointed at the trails, but… Then it just… disappears…" He tapped the screen and looked up at Hank in confusion.

"Did he go underground? Or up in the air?" The director questioned.

"I don't think so… We would still be able to trace the energy reading... It's confusing, it's like the alien just… vanished. I can't explain it."

"Are we sure that this… energy is generated by the alien itself? Or could it be something he's doing instead?" Hank asked

"You think it might be expending the energy in certain ways?"

"Yes, we already know that his body is in itself some kind of weapon, maybe this radiation is linked to the firing of that weapon…"

"Well for now we have no way to track it when it's gone dark, but I've recalibrated the DEO's sensors so we will know where he is as soon as whatever he does that generates that radiation… starts…" Winn explained, tapping a few more keys to zoom back out and show the entirety of National City.

"Good work." Hank slapped Winn on the back "Keep me informed of any progress."

"Will do boss."

"If you don't need us at the moment, we're gona go out for food." Alex half questioned as Hank turned to face the couple.

"Sure. There's not a lot any of us can do until the alien resurfaces again and Supergirl has finished recharging." Hank answered, waving them off.

"OK, we'll be at China Palace if anyone needs us" Alex called out over her shoulder as they left, she tucked her hand into Maggie's and leaned her head towards her "I'm glad you know…"

"What? About Kara?"

"Yea, I don't want there to be any secrets between us."

"I'm glad I know too, I'm just shocked it took me so long to figure it out!"

"Well you've only met Kara a handful of times…" Alex tried to reason.

"Exactly! And her disguise is awful!" Maggie chuckled "It's a good job I can't tell anyone about all this" her free hand wave around encompassing the DEO "The guys at work would never let me live it down!"

Alex just laughed, shaking her head and feeling grateful that no one else had put two and two together about Kara and Supergirl… she really did need to have a chat with her sister about secret identities being at least a little challenging for people to figure out.

Twenty minutes after Alex and Maggie had left on their super important errand to obtain potstickers, Winn started yelling from his terminal.

"Directooor!" He was frantically tapping at his keyboard, sending the visual data to the main screen. Hank appeared, seemingly out of nowhere, behind him.

"What is it?"

"The alien! It's back!" Winn pointed to a sector of the city which was now lit up on the screen with the radiation generated by the beast. The glow was brighter than any trace they had seen before and if anything it was growing brighter by the second.

"Supergirl!" Hank called out, and within a few seconds Kara was standing behind him, sufficiently charged to allow her the use of her super speed once more.

"What? Is it back?"

"Yep…" Winn pointed at the screen

"That's near L. Corp…" Kara spoke nervously "It will be full at this time of day… I need to warn Lena!" She was about to take off when Hank grabbed her arm.

"Kara…" His voice was serious; he rarely used her true name at the DEO, "Alex and Maggie left a while ago… And they were heading to China Palace…"

Kara's face dropped as she realised what Hank was saying, she looked up at the screen where Winn had zoomed in to focus on L. Corp and the surrounding buildings. The overlapped radiation signal was visibly moving closer to the L. Corp tower, and a couple of doors down… stood China Palace…
