"Are you sure this is a good idea?" Lena asked as Alex slipped the Pink Kryptonite into Supergirl's costume.

"Do you want to find out if she's into you, or not?" Alex asked back, and when Lena could only nod, Alex gave her a smug smirk before continuing her work, lining Supergirl's outfit with the Pink Kryptonite chips.

Rumors had been circulating for quite awhile now that Supergirl may, or may not, have had rather strong feelings for the local Luthor, and now, Alex had finally come up with a solution to put those rumors to rest one way or another. She had revealed to Lena that there were multiple types of Kryptonite and one of the rarer kinds, pink, would be exactly what Lena needed to get some answers. If Lena wanted to know whether or not the rumors about Supergirl's feelings for her were true, all she needed was a little bit of Pink Kryptonite...

"Well, if you know so much about it, why haven't you tried it yourself?" Lena had asked when Alex came to her with this proposal.

"Because I don't know how to make it," Alex had admitted. Alex had actually wanted to try the Pink Kryptonite out on Supergirl for quite awhile now, but since she had neither the knowledge nor the resources to make Pink Kryptonite for herself, it had only been a blissful dream for her. But now, with Lena Luthor in the game, Alex had a shot at making her dream a reality. If there was anyone out there with the brains and the tools to figure out how to make Pink Kryptonite, it was Lena. And once Alex managed to get Lena to agree to this wild scheme, Lena did not disappoint.

Now here they stood, a couple weeks later, the plan finally going into motion.

"Now all we need is for some disaster to strike, and then, when Supergirl comes, we'll let the Pink Kryptonite work its magic!" Alex declared once she finished sprinkling the last bits of the pink rock into Supergirl's suit. Lena still looked a bit reluctant to expose Supergirl to Kryptonite, but after numerous reassurances to Alex that it would not harm the Kryptonian, Lena had finally relented. Now, as she watched Alex pack Supergirl suit away again, she could feel a flicker of fear burning in her chest. But it was not fear about what the Pink Kryptonite would do to Supergirl. It was a fear about what it would do to Lena. What would it show Lena? What would this stuff reveal to Lena? And how? And would she be able to tell?

Alex said the signs would be obvious, but what did that mean? Would Supergirl start making out with her on spot? While Lena had to admit that it was a nice idea, the mere thought of its suddenness made Lena mildly uncomfortable. Or what if it had the opposite effect? If it turned out that the rumors were false and Supergirl had no feelings for her, would Supergirl go flying away from her faster than a speeding bullet? That idea wasn't very pleasant to the Luthor either. But as Alex refused to reveal anything more to her about how the Pink Kryptonite would work, Lena forced herself to be content with what little she did know about the substance and wait for life to reveal the rest...

A couple days later, the opportunity at last presented itself for the big reveal. It was a small disaster, an attempted robbery on one of the smaller banks towards the edge of the city, but Supergirl showed up anyway. To her, no crime was too big or small to ignore. So long as she knew it was happening, she would be there. Today was no exception. Once Supergirl got to the scene, she managed to put down all five of the robbers in mere seconds, earning herself a hearty bout of cheering from all the relieved bank visitors and workers. Conveniently among them was Ms. Luthor herself (Alex having sent her over the moment she found out about the robbery).

"Well, I must say, Supergirl, that was quite the rescue," Lena made her presence known to the Girl of Steel who turned around with a pleased and surprised smile when she heard that familiar voice.

"Ms. Luthor! I didn't realize you were here," said the Girl of Steel, but there wasn't any distrust or wariness in her voice. But then again, there wasn't any obvious signs of infatuation. At least none that Lena could detect.

"Well, I was hoping to set up some sort of joint account between L-Corp and the banks of National City," Lena replied. "But I wanted to start small before I tried tackling our larger banks," she added. Although this was not entirely the truth, Lena having only been here today thanks to Alex, it wasn't entirely a lie either. Lena really did have a hope to invest some of her money in all of National City's banks so that if anything ever went under, Lena could loan some of her fortune to them to keep them afloat until this potential economic crisis could pass.

"Ah, well, that's very good of you," Supergirl replied as Lena finished explaining her business here today.

"Thank you," Lena smiled genuinely. "And it is very good of you to come save us so quickly, so that there would still be a bank to invest in once the day was out," she added with a dry laugh as she gestured to the room around them.

"I am only doing my duty," Supergirl shrugged, but she gave Lena a grateful nod as well.

"That's more than quite a few people do, Supergirl, don't sell yourself short," Lena replied. "And your duty is a very noble one."

"You are too kind," Supergirl smiled back at her, but Lena couldn't tell what that smile meant. Was it a polite response? Or something more?

"I only speak the truth," she answered, trying to coax more out of Supergirl. Supergirl obliged, coming back with another polite remark.

For the next few minutes, Lena continued to try and read something, anything, that would make it obvious if Supergirl was into her or not. But the longer as their idle chatter went on, the more disheartened Lena became. Perhaps this was the clear sign. Supergirl's own lack of reaction may be what Alex had been referring to as a sign that Supergirl, despite the rumors, had no romantic feelings for Lena. It was pretty hard to miss how formal Supergirl was behaving with her. That was a sign clear enough. Although part of Lena was not surprised, a surprisingly large part of her was mildly disappointed by this revelation that Supergirl didn't have any feelings after all.

"Well, I suppose I shouldn't be taking any more of your time," Lena said, finally deciding to bring their talk to a close.

"Nonsense," Supergirl replied airily. "You never take up any of my time! I'm always happy to speak with you, Ms. Luthor!" and it was clear that the Girl of Steel meant every word she said. Lena felt conflicted. On the one hand, this was a very sweet thing for Supergirl to say to her, but on the other, the fact that she still used a formal name when talking to Lena made it clearer that Supergirl was only saying this out of respect and friendship, but not out of any personal desire to spend extra time with Lena. Supergirl's tone, when she had said this to Lena, had been purely formal, nothing to mark any sort of infatuation or attraction at all.

But even though Lena was willing to admit that all the signs that pointed against Supergirl being interested in her were clear, Lena still wasn't ready to admit that she had made peace with such an idea. On the contrary, although she respected Supergirl's lack of an interest in her, it still disappointed her to think that Supergirl didn't feel anything at all for her. Lena really had hoped that Supergirl's admission about wanting to spend time with her would've been more than just a polite remark, but alas, it was not to be. Instead, after a few more seconds of polite chatter and a formal farewell, Supergirl flew away and left Lena to stare longingly after her.

"HA! YES! I KNEW IT!" Alex sounded triumphant the moment Lena called her to tell her how the talk with Supergirl had gone. As if she wasn't feeling bad enough, Alex's obvious enthusiasm about Supergirl's lack of feelings for Lena made Lena wilt even further. Of course. She should've known Alex wouldn't have been interested in trying to get her in Supergirl's good graces. No doubt, Alex was one of the people still averse to the idea of a Luthor and a Super together, and this confirmation of Supergirl's lack of feelings for Lena was probably a huge relief to-

"Oh man! She is SOOOOO gay for you!" Alex laughed a few seconds later, and with that one little phrase, Lena's whole preconceived notion about how her reaction with Supergirl had gone went right out the window.

"What?" was all Lena could think to say in response.

But by the end of Alex's explanation, Lena was feeling a lot better about herself. From what Alex explained, Pink Kryptonite, strange as it sounded, actually turned Kryptonians gay.

"But then, shouldn't that have made Supergirl more interested in me?" Lena had asked in confusion. "Or have turned her straight?"

"Not necessarily," Alex replied. Then she explained. "From what I've read about the Pink Kryptonite, which isn't much, admittedly, it sounds like it turns straight Kryptonians gay, but doesn't have any effect at all on gay Kryptonians. Consider it a one-way-street type thing, ironic as that is. But that's exactly what I was banking on!" and Alex didn't need to explain any further for Lena to understand. Of course! It was brilliant!

If Supergirl had been entirely heterosexual, the Pink Kryptonite would've resulted in some very obvious behavioral changes around women. But, since nothing at all seemed out of the ordinary to Lena, that at least proved that Supergirl was in fact gay (or perhaps bisexual, there hadn't been any study done on what Pink Kryptonite did to bi or asexual people). Supergirl's inaction had been the very obvious sign that Alex had been referring to earlier. For once, inaction meant reaction. By experiencing zero emotional or behavioral changes in response to Pink Kryptonite, Supergirl had just proved that she was queer to at least some degree, and given that she had zero changes around Lena...

"It means that the way she's been treating you before has been just the same as ever! It means that the way she's been treating you in the past has been the exact same as the way she treats you while under the influence of Pink Kryptonite! She's gay for you, Lena!" Alex cackled gleefully. "Oh, I knew it! I knew it! I knew it!" she sounded like she was over the moon, and Lena had to admit that she felt exactly the same way.

AN: Because IDK what Pink Kryptonite does to an already-gay Kryptonian, let's imagine that it actually causes no reaction at all (think of Pink Kryptonite as a one-way street), so Alex knows that SG is gay because she doesn't seem affected by the Pink Kryptonite. She's already there! LOL. Sorry, IDK, I just got the random urge to write about SuperCorp and Pink Kryptonite, so here's the end result.

And just a heads up, each chapter is its own separate story. I just combined them all into one fic since they were all born of the same idea.
