It's... unpredictable

And... embarrassment!

Erin stared. Supergirl stared back, unblinking. Erin shifted. Alien. Ok. Who knew what effect her power would have on a non-human mind-

There was a blur of blue and red, and suddenly Supergirl was no longer standing in front of her.

Ok. That was... probably good. If nothing else she didn't have the super-powerful alien trying to stop her any more; she just had to worry about Alex.

Erin quickly turned her attention back to the brunette, opting this time to go for 'never.' As always tended to be the case when someone had been stripped, the last thing Alex wanted to do was bare everything.

So suddenly Erin was greeted by a full-frontal view of the agent's slim, toned body, Alex's face flushed and humiliated-

And there was another yelp. Distracted by the sound, Erin turned-

To see another naked woman. Wait, what? She hadn't-

Another shriek, further down the street; Erin turned her attention, frowning. She was sure she hadn't...

But, somehow, one by one, women down the street were losing their clothes. In the blink of an eye they went from fully clothed to completely exposed, still taking a moment to react. Was... was that just something that happened on this Earth? Erin blinked.

No, wait! She spotted the latest to end up naked, and glimpsed a sudden blur.

Was that Supergirl?

Erin almost laughed. Somehow her influence had gotten jumbled up in Supergirl's alien brain; instead of making Kara feel embarrassed, she'd somehow gotten Kara to want to make other women just as embarrassed. That was perfect. That was bloody amazing-

And then she felt something hit her in the back. Her last thought before slumping over was silently cursing that she'd let herself be distracted.

Behind her, Alex lowered her weapon, one of the DEO's non-lethal arsenal made to stun, still blushing furiously as she watched the newcomer collapse.

"Someone bring her in!" Alex shouted, voice cracking slightly. "I'll- I'll follow you back."

Bright red, she crouched to struggle back into her suit.

Erin awoke inside a forcefield. She blinked; tentatively she reached out with one hand, only to see the air spark. Quickly she drew back.

On the far side of her cell was the woman she'd identified as Alex, unfortunately dressed again. Erin focused; maybe friendship first, get Alex to let her out, then get her naked-

"If you're trying to use your powers, don't bother," Alex said. Her cheeks were still a little flushed from the memory. "A Martian couldn't get past the psychic dampeners we've put up around you."

"You have Martians here?!" Erin said.

Alex paused.

"Tell us what you did to Supergirl," Alex said. "Since running into you she's been going all around the city, doing... that, like you did to me. You're going to tell us what you did, and tell us how to fix it."

"Why?" Erin said. "Honestly this is the best bloody thing that's ever happened to me. Someone with the speed I saw dedicating themselves to getting every woman naked? Tell me how that's anything other than a party."

"One," Alex said, impatient. "You're not going to get to see any of it. You're going to stay locked down here until I give the say-so."

"Oh, but I can imagine," Erin said. She beamed. "Has she gone after you again? I saw how you looked, definitely top shelf, I can think about you ending up-"

"Two," Alex interrupted again. The fierce blush in her cheeks answered Erin's questions. "She's stripping women. You're a woman. You think this'll go much better for you?"

Erin hesitated.

"Honestly, almost worth it," Erin said. "But... convincing argument."

"Then tell me what you did," Alex said.

"At the risk of being a cliche, this has never happened to me before, I swear," Erin said. "First time trying to affect an alien, turns out aliens aren't the same as humans. Who knew?"

"Then what were you trying to do?" Alex said.

"Get her naked, what do you think?" Erin said. "You saw what I did to you."

Alex paused. She took a step back, putting her hand to her ear to use her comm.

"You hear that Brainy?" she said. Then she turned back to Erin; "You're going to help us undo it."

"How?" Erin said.

"We're going to figure out how whatever you do works, apply it to brainscans we've taken of Supergirl, and then figure out some solution," Alex said.

Wait, why did Alex's voice suddenly sound rather more shaky?

They just wanted to figure out her powers. Which... Erin suddenly grinned. Which meant they'd need examples, they'd have to see it in action.

"Let me guess, you want to see the boring effects on brain activity when I influence someone," Erin said. "Who's volunteering to get naked, then?"
