Ah, Jane was a materialist... if only he could read her thoughts!
"I don't believe in ghosts the way that other people do. There's a perfectly rational scientific theory, in fact." he brought his hands out in front of him for her to see, flicking the cuffs of his sleeves up with a sharp twist of his wrists. It was so that the sleeves of his tail coat would ascend his elbows without farther effort. He was such a lazy lout. "Say that my left hand is the past, my right the present. Time is non-linear, but spacetime is one big, tube-like room on the outskirts of reality. Time also has a wacky way of informing itself, or whispering little secrets to the present--which can't be depicted here not only because I don't have a third hand, but also because it isn't here yet--to the future. And although the past can't be altered, it has been shown to communicate with the present. At least on a very delicate, quantum level. It's a very long explanation..." he pressed both of his hands together, fingers interlacing. "Time looks more like this, than separated. It's called entanglement."
To distract her from immersing herself into the cooling idea that his jargon was tedious and tiresome, he ventured to reach behind her ear, though he did not touch her. Not an accidentally phantom stroke of the cloth edge of his sleeve, nothing. And produced a red rose which he offered it to her at once. Yes, he did keep these up his sleeves. And for just these occasions. "You can leave it at someone's door. How nice for them to wake up and find it."
How drab these people's doors were. How drab these people's hallways were. They needed something... something odd. Something that made no sense. Ah ha! Flyers! Flyers for... he'd test it out on Jane first. Many comedians do this, examine reactions first, and of course, with the utter seriousness with which a comedian summons to tell one of his tall tales, Miles inquired deliberately and genuinely:
"Jane? ... have you seen a king cobra around here by any chance? It was in my basket this morning and I haven't been able to find him ever since. He comes to the name Ra."
