Three..? Seemed a waste to use money on her. Larséne shrugged to herself with a smile, resting calmly on her cane as she watched Demetri purchase the tickets. She could easily just have snuck on if she wanted to enjoy the ride or travel in the shadows of the train, but then, maintaining a role as a human meant taking to all the little human customs. She gleamed a wide grin when she was given a chocolate bar,
"Oh you sure know how to treat a girl.." She responded, rolling it around softly in her hand, the idea of visiting an entire candy store was a delight indeed. The demoness revelled in the idea as she followed the detective to their cabin, where she did indeed sit down, quietly, obediently. Delicate movements peeled the wrapping away, fingers gently tugging it apart before she softly broke off a bit, smiling quite contentedly at the rush of sweetness, the aroma generated as it warmed on her tongue, rolled about softly, slathering it across her taste buds.

Having taken a human form was probably one of the best things she'd ever done, but her enhanced senses made something like this an absolutely pleasurable delight, not that she'd ever admit it. Her cane was rested against the window as she leaned back comfortably, rolling her shoulders softly and chuckling to herself. Yes, she had a penchant for that. It bothered people who weren't used to her. No-one really could understand what went on in that mind of hers.
Demetri had been around her so long that it had become something of a tell. Certain ways of laughing meant she was happy, other times she was annoyed, this was a pleased chuckle. Satisfied by the candy, the promise, the fact that they were finally getting out and about.
She could go with Demetri to go pester that man, the detective's friend. She adjusted her glasses calmly and looked out the window at the crowds at the station. It wouldn't be long before they were gone from this place. She wouldn't miss it, being in one place too long was boring.. Far too boring..
