childish wonder, case one, irish tourists:

Aka. Posh cars should come with men in suits
'I'm not a monster'

Leatrade was gathering his things from his desk when the sound of a sleek car pulling up outside caught Rosalie's attention. She peeked through the blinds, a mischievous smile forming as she spotted the polished black vehicle.

"Ah, the 'posh' car's here," Rosalie remarked, her voice dripping with playful sarcasm. "Well, well, well, Lestrade. I see someone's got a secret they think is still a secret. That divorce really changed you, Greg."

Lestrade glanced over at her, clearly not in the mood for her jokes. "It's not like that, Rosalie," he said, trying to keep his voice steady as he grabbed his coat. "The car's just a ride, that's all. Mycroft sent it. We need to discuss Sherlock."

Rosalie raised an eyebrow, clearly unconvinced. "Oh, right. Discuss Sherlock. Sure, I'm sure that's all that's going on," she said, leaning back casually against the doorframe, arms folded across her chest. "Nothing suspicious about Mycroft sending you a private car for that, no sir. Just a regular 'business' thing, huh?"

Lestrade's expression hardened slightly. "It's not like that. Honestly. Mycroft's just making sure I get there in one piece. He's concerned about Sherlock, and you know how he is." He gave her a pointed look. "You don't have to make everything weird."

Rosalie snorted, crossing her arms with a smirk. "Oh, I'm not the one making things weird. It's Mycroft and his fancy car that's doing all the talking for me." She let the words hang in the air for a moment. "I mean, what else would two grown men be talking about in a posh car if not... you know... feelings?"

Lestrade sighed, clearly exasperated with her teasing. "We're talking about Sherlock. He's been... unpredictable lately. Mycroft just thinks I should be more careful about how I approach him. That's all. And Mycroft isn't in the car."

Rosalie gave him a skeptical look. "Uh-huh. Sure, that's all. And Mycroft just so happens to send you a fancy car to have this... discussion?" She raised both brows, unconvinced. "Look, Greg, I'm not stupid. We both know there's more to it than that. But whatever. If you want to pretend, go ahead. I'm just gonna sit back and watch."

Lestrade rubbed his forehead, his patience thinning. "I'm not pretending, Rosalie. I just—" He stopped himself, shaking his head. "You wouldn't understand."

"I understand more than you think," Rosalie said, her voice softer now, a hint of genuine curiosity beneath the teasing tone. "But if you're not going to tell me, then I guess I'll just keep having fun with it."

Lestrade hesitated for a moment before sighing in defeat. "Fine. You can keep making fun of it. But it's not a relationship, alright?"

Rosalie's grin widened. "Yeah, yeah, sure. Whatever helps you sleep at night." She wagged a finger at him teasingly. "But don't forget, Mycroft's the one sending you around in the luxury cars, not me. Just saying."

Lestrade shot her one final, exasperated look before turning toward the door. "Don't make me regret this, Rosalie."

"Make sure you send me a selfie with you and Mycroft, okay? So I know you got there safe." she called after him, her voice carrying the last word with a mischievous lilt.

Rosalie leaned back against the desk, a satisfied smirk still playing on her lips. She wasn't convinced for a second about the whole 'just a discussion' story. But that was half the fun—knowing that she could get under Lestrade's skin and still get nothing but mystery in return.

Lestrade leaned against the doorframe, glancing at Rosalie as she continued to smirk at him. "Alright, look—if you're done making fun of me, you might as well grab your things. I'm heading out now, and if you want a lift home, you'd better get moving."

Rosalie's eyes widened at the mention of a lift, her earlier teasing immediately falling away. A lift home, in a posh car no less? She didn't even need to think twice. The prospect of being chauffeured in a luxury vehicle was way too tempting to pass up.

"Oh, now that is an offer I can't refuse," she said, her voice suddenly lighter as she grabbed her bag and swung it over her shoulder. "I'll just take the ride. Can't say no to a fancy car when it's practically begging me to climb in."

Lestrade raised an eyebrow, clearly not expecting such a quick change of attitude. "I thought you were all about making fun of the car?"

"Yeah, well, that was before I realised I could be in it," she said with a shrug. "I'm not going to let the opportunity pass me by. I'm not a monster." She flashed him a wide grin, already heading for the door.

Lestrade sighed, shaking his head. "You're impossible, you know that?"

"Impossible? Me? Nah. Just incredibly opportunistic," Rosalie replied with a wink.

Lestrade couldn't help the small chuckle that escaped him. "Right, right. Come on then, let's get going before you change your mind again."

Rosalie gave him a dramatic salute before following him out of the office and down the hallway. As they made their way outside, the sleek black car was still parked near the curb, the driver waiting patiently.

"Posh," Rosalie muttered under her breath, eyes gleaming with curiosity. "So, are we taking a detour to Buckingham Palace, or is this just your average date with Mycroft?"

Lestrade ignored her, opening the back door for her. "After you."

Rosalie slid into the backseat, sinking into the plush leather seats with a satisfied hum. She adjusted her bag on her lap, looking out the window, the reflection of the city streets flashing by. She couldn't help but feel a little smug.

The door clicked shut behind Lestrade as he climbed in beside her. He gave her a side glance before turning his attention back to the front.

"I'll admit, this car's pretty nice," Rosalie said, stretching out her legs and leaning back, clearly enjoying the comfort. "Maybe I'll just take the long route home today."

"You'll still have to get out eventually," Lestrade muttered, though there was a small smile tugging at the corners of his lips. "Don't get too comfortable."

Rosalie rolled her eyes playfully. "I'm just here for the ride, Lestrade. No harm in enjoying it while it lasts."

As the car began to move, Rosalie looked over at him, her expression softening for a moment. "But seriously, thanks for letting me tag along. It's not like you had much of a choice, but you could've said no."

Lestrade glanced at her, his tone shifting slightly. "You don't give me a lot of options, do you?"

Rosalie grinned. "That's half the fun, right?"

Lestrade shook his head, a resigned laugh escaping him as they continued the drive. Rosalie settled back again, content for the time being. At least this was a distraction. And with the way the day was shaping up, she'd need a lot more distractions to keep her mind off of things.

As the car rolled down the streets of London, the city buzzing around them, Rosalie couldn't help but let out a little sigh of contentment. Maybe, just maybe, this ride would be the highlight of her day.
