Stacy comes into the room

At that moment, Stacy barges into the room, a bottle of wine in hand.

Stacy: "Heyy, if it isn't my rockstar saleswoman! You out here eating reheated leftovers like usual?"

Sophie 1: "Well I was gon-"

Stacy: "That just won't fly! C'mon we'll have lunch together. I'm buying. I'll-..."

Now she sees that there's a Sophie standing at the doorway and sitting at your desk.

Stacy: "...Well I'll be a tarred and feathered burlesque dancer, you never told me you had an identical twin sister!"

Sophie 1: "We're identical triplets, if you can believe that."

You feel that it's good to claim this well in advance, so that you'll have some leeway if another clone appears.

Stacy: "And does... why's she wearing a suit too?"

Sophie 3: "I work as a sales rep at Häagen-Dazs."

Another good lie. You're practically addicted to the ice cream brand in question, and have toured their factroy headquarters. You'll be able to give cursory answers if Stacy makes follow-up questions, or at least make up convincing additional lies.

Stacy: "So what brings you here?"

Sophie 3: "I'm here on official business."

Sophie 1: "Yep. They're looking to set up a new factory in Denmark."

Sophie 3: "Thought that it'd be prudent to contact my sister directly."

Stacy: "That's fantastic! We can discuss the details over lunch, how about it?"

Sophie 1: "Of course."

Sophie 3: "Naturally."

You don't show it outwardly, but you're both panicking hard. You have to be able to coordinate your lies very carefully to remain consistent. Thankfully you're both the same person and have identical memories. You both follow Stacy to the company food court, and order a chicken salad each.

Stacy: "So uh, what's your name?"

Sophie 3: "My name's Tammie."

Stacy: "Aha. You mentioned that you're triplets. What's your sister's name? Where's she work at?"

Sophie 1: "Her name is Allie, and she works as a stock trader."

Stacy: "Wow, your family's got business acumen outta wazoo."

Sophie: "You could say that. We all went to the same business school together."

Stacy: "So Tammie, where do you live, again?"

Sophie 3: "Well the Häegens-Dazs HQ is in New York, but I live in Hoboken, New Jersey and commute from there. It's way cheaper than living in central New York."

Stacy: "And Allie?"

Sophie 3: "Oh she lives in Soho, 'cause she makes a mint. She's a bit of a showoff like that. We both came here on the same flight to visit our parents, since I was coming here too."

The two of you are slowly building a character profile for 'Allie' before her inevitable debut.

Stacy: "Oh, she's in town too? Can I meet her?"

Sophie 3: "I dunno, it's difficult trying to pull her off the phone. Why don't you try calling her, Sophie?"

Sophie 1: "Ey sure."

Sophie 3: "I'll be back in a second, I'm just gonna get one of those apple fritters too."

As you dial your home number again to speak with Sophie 2, you see it happening: as Sophie 3 gets up from her seat, another Sophie stays seated in her place. A new clone just appeared out of nowhere. Stacy happened to be turned towards you at the time, so she didn't see it. Now your new clone has to think quick. Hopefully she realizes what happened. You disconnect the call immediately, so that Stacy doesn't begin to wonder why 'Allie's' phone isn't ringing.

Sophie 1: "Allie!"

Sophie 4: "Hi Sophie! Gosh you're not easy to find, I thought you'd be at your office."

Stacy is bewildered at seeing the third 'sister'. She could swear that this is just Tammie, who never even left her seat. But then she swivels around in her chair and sees Sophie 3 at the counter ordering an apple fritter.

Stacy: "What the-... Fuck my insides and outsides, you're really identical! How can you even tell each other apart?"

You smile deviously.

Sophie 1: "By name, of course."

Stacy: "Yea but like... ah, forget it. It's a pleasure to meet you, Allie."

Sophie 4: "Pleasure's all mine."

Sophie 4 shakes hands with Stacy. This situation's getting out of hand, fast.
