Get a costume first

You chuckle quietly, wondering what's about to happen, and you raise your hand to the door of Carmen's office but stop yourself at the last moment. No, you realize you can have a little fun without getting into trouble with Bruno, so you activate your magic ring to stop time, and then you teleport away to the costume store you had gone to the night you had first met Carmen. Once you're there, it's easy to find and change into the exact same Zorro costume and mask as before that you used to get into the exclusive club. Once you're done, you teleport back to outside Carmen's office and let time resume.

This time, you don't hesitate and knock on the door confidently. There's a pause before Carmen calls out from inside.

"Who is it?"

"An old friend!" you announce, loud enough for her to hear you. Just in case, you look around to make sure nobody else is around, but it's way too late for anyone to be in the office.

Again, there's a long pause, before you hear footsteps behind the door. The handle turns and the door opens outward slightly, just enough for Carmen to poke her head out sideways.

"Hi!" you greet her with a smile.

Carmen doesn't say anything, but her eyes are wide in surprise or shock, and her mouth is open with a stunned look. You don't need to ask if she remembers you from that night at the club, because she clearly does. It takes a moment for her to get over her initial shock, before she raises a hand to cup her mouth and lower half of her face, realizing that unlike that night, she's not wearing her mask right now.

"Yeah, it's a little late for that. I know who you are, Carmen. And what you do during your free time at night," you say with a sneer.

Knowing that you're right and that there's nothing she can do to hide her identity, Carmen lowers her hand so that she can speak. "Who are you?" she asks.

"Yeah... I'm not going to tell you," you reply.

"How did you find me? How did you get past security... dressed like that?"

"Nope. I'm not here to answer questions. I'm pretty sure I hold all the leverage right. I could easily expose you as the vigilante that you are, the rich daddy's girl by day, ninja warrior lady by night. I could ruin your life," you say.

Carmen tenses up as she realizes the position she is in. "Fine. What do you want?"

"Aren't you going to invite me in? I know you're in your costume and getting ready to hit the streets."

Carmen blinks and looks around behind you, before she shakes her head in resignation and steps away from the door, allowing you to enter. Indeed, when you step into her office and close the door behind you, you see that she's changed into her full ninja outfit now, although she's not wearing any shoes. They're by her desk.
