She freaks out and runs away from Lena

Kara's face is quickly going from the blush of excitement to a deep red of mortification "I.. uh, Lena this isn't, I mean, we're not.. not that it'd be wrong, or is wrong.. but I don't- I have to go!"

Kara jumps out of the chair and runs out of the room, her dress falling down from where it was bunched up around her waist.

Lena looks at the still open door, her face quickly hardening as her smile melts away "Fucking holier than thou Kryptonians, so she thinks she's too good for me, as if! I'll make sure both she and the rest of the world knows she's not better, not even close!"

Meanwhile a disheveled Kara is hurrying across the lounge and into the bathrooms, making a beeline for the sinks.
'That was close, I almost... with Lena!'

Dropping her mask on the counter and then throwing some cold water in her face, Kara stares at her reflection 'Would that really have been so bad though? She's my best friend, but I've often felt butterflies around her, could we be more? ...oh Rao, she offered herself, physically for sure, maybe more, and I... I ran away as if it was some horrible insult... oh no, oh no... what have I done! I'm a horrible person... I need to fix this!'

Turning abruptly from the mirror and bolting towards the door Kara runs straight into a woman who just entered the bathroom.

"Ouf, I'm sorry, I need to... Ms Rojas? You.. I... I have to run!" Kara pushes past Andrea and runs out of the bathroom, the older woman looking after her, then over to the mask on the counter "Interesting, maybe she can be of some use after all."

Reaching the room they were in earlier and finding it empty of both Lena and her clothes Kara turns around and runs back towards the club entrance.
As soon as she reaches the reception area she spots Mark at the desk and runs over to him "Mark, hi! Did you see Len... I mean a raven haired woman in a red dress with a lot of... er... décolletage? I need her.. to talk to her!"

Mark raises an eyebrow at Kara's disheveled look and then points to the door "I don't know why you'd want to have anything to do with her, but as she exited I heard her call someone about a ride. But really though you-"
"Thanks Mark but I don't want to hear it, you shouldn't judge her like that!" grabbing her phone, purse and credit card from box #42 Kara runs out onto the street.

Exiting the club Kara hurries down the short stairs and starts desperately looking up along the street, seeing no one in red she turns and sees a person in red just vanishing around the corner of the block quite some way down the street. Seeing her at risk of disappearing, Kara immediately starts running after her... for all of five steps before she stops.
'Frigging cobblestones, why didn't I just wear something comfy, eww, I'm washing my feet in bleach when I get home' taking her shoes off and carrying them, she sets of at a dead run, her bare feet slapping on the cobblestones and in puddles as she races toward the corner.

The narrower street that the woman in red vanished down is not very well lit, but still well enough that she can see it's empty. Half way down though there's an alley branching of to the right that the woman could've reached from this corner in the time Kara used to get here.

Hesitating for a second, Kara then sets of down the narrow street, almost managing to avoid all the puddles and refuse as she heads to the alleyway she hopes Lena entered
'Ouch, what the... I need to tell the mayor his street sweepers suck... ignore it and keep running, you'll heal by tomorrow anyway. Just a little longer now!'

Kara runs around the corner to the alley, favoring her left leg. Not far into the alleyway she sees a man standing next to a car, and the back of a woman in red climbing into it.

Sprinting as best she can over to them she swerves around the man and grabs for the woman's hand blurting out "I'll have sex with you!" too late realizing that in her hurry, her attempted grab instead became a push, sending the woman head first into the car.

As the man grabs Kara by the neck, she sees the woman's face as she's climbed up from the floor of the car and turned around.

'Uh oh!'
