The trouble is that the scene isn't all in one email chain and Chipotle Verde doesn't show up immediately.
I found this much. Unless something's missing they didn't get very far with snooping, and getting called to Chipotle's office must be a different scene.
As Hazel Naught requested another card, Scarlet Spectrum spotted the briefest flinch from Red. "Well, if I win, you'll need to tell me about where you work." Then the hands were revealed. Hazel Naught had two aces and a face card, causing a situation where in order to not bust, the two aces would automatically downgrade to 1s. The dealer had a 6, 4, and 9. Red revealed an ace and a 7 for one hand but two face cards for the other, meaning he tied with Scarlet Spectrum! He was about to comment but then the stallion at the end who had been quiet about all this revealed his hand--a face and an ace for a perfect blackjack! He grinned and said, "A shame really, I actually did want to know the answer to the question. But some days luck is more slippery than a roulette wheel covered than melted shortening."
Just then, an alarm went off and a tall stallion announced, "Everypony out!" Poinsettia Prim stormed over and asked, "What is the meaning of this?" "You hear that alarm. You aren't going to argue with the fire marshal are you?" She grumbled but waved for the employees on the floor to follow her to the emergency exit. Red seemed annoyed at all this. "This game will likely resume in the morning, thus I shall retire for the night. Farewell." As he got up, Dart Noveau bumped into him. After she apologized, he stormed off. She then waved for the others to follow her out of the building, though with Poinsettia Prim out of sight, she quickly gave the dealer from earlier a hug, then dashed off. She whispered to the others, "Back to the hotel, there's a lot to talk about."
Wanderlust's eyes flick between Prim and Darty, and gears churn in his head. The idea that the building is actually on fire never crosses his mind. He quickly grabs Symphony and pulls her into the back area, near the kitchens "We have work to do." He hisses. "Let's get upstairs, then try to look lost."
As the Alarm went off Symphony looked around in a panic, and when she saw the other Employees heading out, she was about to dart off to follow them... that is until Wanderlust grabs her and drags her off. "Hey... Ow... But what about the Fire? We gotta get outta here!" She says flailing as she's pulled to the kitchens.
Around a corner and out of sight from the rush, Wanderlust pauses. "There's...not really a fire, right? I mean, the kitchens are fine. Where else is a fire going to happen? I think someone else has a plan." He grins. "So I'm making their plan my plan!"
"In one of the other rooms? Maybe someone dropped one of those really expensive cigars or something?" Symphony suggests nervously as her rainbow eyes dart about, seeming to look at things that aren't there... She lets out a soft sigh. "So, what is it you're planning?"
Wanderlust shrugs. "Same thing we were already planning: go snooping. If we don't see anybody, we get out unnoticed. And if we do see someone, we follow them and find out why they're still here. We both know something in this building is fishy, and it's not the shrimp, is it?"
Symphony huffs softly and nods. "Alright, whatever you say." She says Still not really sure about this, but doesn't seem like there's any other option here. "So where do we start?"
Wanderlust looks Symphony right in the eye. It's the same appraising gaze he gave Scarlet a few days ago. "We're a team; if you don't want to do this, we'll leave. But if you do...we'll see less ponies upstairs."
Wanderlust and Symphony heard a female voice calmly ask, "¿Qué estás haciendo?"
Symphony looks to Wanderlust, her rainbow eyes sparkling, but looks away at the voice and turns to face the mare, not giving Wander a proper answer. "I um... Uh... Sorry... I uh... Don't speak... um... Habla no espanio?"
"Aaahh..." The mare wasn't exceptionally tall but she did have a slight edge on Wanderlust and Symphony. She was a green pegasus wearing one of the casino uniforms and a necklace with a brilliant orange jewel. She was smiling and seemed to be sizing them up. "So, as your boss...I was wondering just what the two of you were doing while an alarm was going on?"
Wanderlust had been moving very deliberately, carefully! acting like his heart hadn't just tried to leap into his lungs, but that got his attention. "Our boss is Poinsettia Prim." He says, suspicious.
She chuckled. "Prim is your immediate supervisor. I am Chipotle Verde, owner and general manager. She answers to me. In turn, you didn't answer my question..."
"Ah, well I was panicked over the alarm, and Wander dragged me in here... and uh... I was kinda just asking him the same thing..." Symphony replies softly with a bow of her head as she passes the buck, while remaining mostly honest besides she couldn't lie to save her life...
With adrenaline roaring in his ears, Wanderlust is proud of how well he keeps his cool. "Now panicked is an understatement, darling!" He pulls Symphony close (and slightly farther from Chipotle Verde) in a protective gesture. "She was having a full on panic attack! She could hardly breathe! I wasn't certain she'd make it through the crowd, so I figured I'd pull her back over here and calm her down a smidge before leaving."
Chipotle Verde looked over the two before saying, "Very well, wouldn't want any little ponies to get hurt, would I?" She then calmly motioned a wing towards the exit. The kitchen had its own, presumably so the cooks wouldn't need to move through the crowds and due to the fact that the kitchen itself was the place a fire was most likely to start.
Symphony blushes a bit as Wander pulls her closer. "Ah yes, well now it seems like we'd better evacuate..." She replies softly, looking to Wander. Whatever her feelings on snooping were, it doesn't seem like that was happening now, and she certainly didn't want to upset this pony by not following their orders, that felt like it would be very bad.
Now Wanderlust might have been easily excitable, but they weren't stupid. They knew when they were caught, and they knew when they were getting a pass. "Yes, dear, let's go." He starts walking towards the exit.
After slipping out of the kitchen exit, Wanderlust and Symphony quietly made their way back to the hotel.
Gosh. Amber and Static played off of each other so damn well here.
