A/N: Welcome back to another story of mine. "Virus" had a lot of views and just oh gosh you guys are amazing. So I'm back at it again with another story/series. Just read and please enjoy.

Kara floats through the air, her eyes scanning over the area as she slowly moves around the perimeter. The breeze flows through her hair and cape as she shakes her head in confusion, before slowly descending back towards the ground. Maggie walks over and looks down at the giant hole in the ground before looking up at Kara.

"What'd you find?" Kara shakes her head, the crinkle still between her eyebrows.

"I couldn't see anything. Whenever I tried to look through the ground my vision would just go dark until I looked away." Maggie's eyebrows raise.

"Well, that's not good. We have a giant tunnel in the ground with no apparent cause that can also blind you." Kara nods, her eyes still trained on the tunnel. Maggie gives her a look before putting a hand on her shoulder. Kara jumps slightly and looks at Maggie.

"We should go to the DEO." Kara clears her throat and nods, following Maggie to her car and sitting in the passenger seat with her. Kara messes with her fingers anxiously as she waits for their arrival to the DEO headquarters, Maggie notices.

"Kara." Kara jumps again at Maggie's voice. "Are you okay?" Kara nods quickly, a smile appearing on her face.

"Of course." Maggie just smiles back, concern still filling the back of her mind. They arrive at the DEO only five minutes later, the uncomfortable silence still hanging in the air as the two women get out of the car and enter the building. Once in the DEO, Alex runs towards Maggie and hugs her. She keeps an arm wrapped around her shoulders as she looks at Kara.

"What'd you find out there besides a huge hole in the middle of National city?" Kara clears her throat again.

"Not much, I couldn't see through it without my vision being messed up." Alex frowns slightly.

"Lead?" Kara shakes her head.

"It didn't just prevent me seeing through it, it completely blinded me until I looked away from the area." Alex is about to say something else before Kara turns her back towards her. "I have to go to the bathroom, I'll be right back." Kara speeds off with Alex watching her.

"What was that about?" Alex asks, looking down at Maggie.

"She's been acting weird since we left the tunnel. She was quiet and pale, but I didn't mention it because she's Kara." Alex nods before sighing heavily.

"She's Kara." The silence hangs between them for a minute before Alex inhales heavily and turns to face Maggie. "Do you have anything else you need to do today? I was thinking margaritas at my place followed by more binge watching of Orange is the New Black." Maggie smiles as she nods.

"I don't have anything else that's more important." Alex beams excitedly as she looks behind her at where Kara was standing minutes earlier.

"I'm going to check on her, but I'll meet you there at 7?" Alex asks.

"7 sounds good, see you later." The two kiss goodbye before they depart.

Alex walks over to the DEO bathroom door that was still locked and knocks on it lightly.

"Kara, you okay in there?" There's no response. Alex tries the handle, the knob still stuck in the locked position. "Kara, please answer me or I'm going to have to come in." There's no answer still, Alex barely catches the sound of a small whimper under the door. With no time to waste, Alex kicks against the door until the knob breaks off and the door slams against the wall. Alex looks down at Kara who's currently splayed across the floor, her eyes barely open.

"Kara! Can you hear me?" Alex kneels down to her barely conscious sister. Kara turns her head slightly towards Alex.

"'M sorry," Kara mutters, looking at the toilet, Alex suddenly noticing what looks like vomit inside. "I got sick." Kara whimpers and Alex looks at her sympathetically. She touches her earpiece and talks calmly.

"I'm going to need medics to come to the bathroom for Supergirl." Alex rubs Kara's arm soothingly as she keeps her eyes locked on her.

"What's going on? What happened?" Winn's worried voice responds through the headset.

"It's not serious, just want to get her checked out," Alex responds, sincerely hoping that this isn't more serious than this looks. Kara looks around, dazed as she tries to sit up.

"Sweetie, I need you to stay down for now," Alex says as Kara nods lightly and lays back against the tile. "Did you lose your powers?" Kara shakes her head, whimpering slightly. Footsteps are heard as three doctors come into the bathroom, starting to check her vitals.

"What happened?" One of them asks Alex.

"She was acting strangely earlier. I think she threw up and passed out. She still has her powers." Alex looks at Kara and squeezes her hand comfortingly. One of the doctors looks at the screen with confusion before passing it to another for confirmation. They both nod before putting away their equipment.

"We're going to need to move her to the med bay. It looks like she's been exposed to Kryptonite." Alex's eyes widen as she looks back at Kara. One of the doctors tries to lift Kara before she whimpers and squeezes Alex's hand tighter. Alex hisses in pain before Kara eases up and looks at her apologetically.

"I can carry her. Move out of the way." Alex picks Kara up and starts following the doctors before she smiles at Kara. "Got to make me do all the heavy lifting, huh?" Kara chuckles slightly, her face regaining more colour as they walk. Halfway to the med bay, Winn runs over and starts shouting out questions at lightning speed.

"I'm fine Winn, I feel better already," Kara reassures him, Winn sighing out in relief. Alex sets Kara down on one of the beds as the doctors start working on her once again.

"When were you even exposed to Kryptonite?" Alex asks a now fully aware and awake Kara.

"I guess there was some around the tunnel. I started to feel a little sick by it and the effects didn't wear off until now." Alex frowns as the doctors finish their work, announcing that Kara was indeed fully healthy and that the effects were indeed temporary. Kara sits up on the bed, her hands drumming against the frame in boredom.

"I don't want to leave you alone like this."

"Like what? I'm fine now, Alex." Alex bites her lip and looks at Kara with worry.

"Can you come with me to my apartment for now? Maggie and I are binge-watching and I really just want to make sure you're fine." Kara is about to deny the request until Alex looks at her pleadingly.

"Fine, but you better have potstickers." Alex smiles as she holds out a hand for Kara to take. Kara climbs off the bed and follows Alex as they head out towards the parked van outside.
