Loki let out an irritated sigh. Long fingers drummed against the arm of the chair he was sitting in. And while he admired Sherlock's rational line of thought and scepticism, it was growing rather tiresome quickly. If he truly wanted to make a believer out of this other man, he was going to have to try a little harder. He couldn't hold back. But what did it matter if Sherlock believed him or not? Perhaps because for a mortal, his mind intrigued and fascinated Loki. Sherlock seemed sharp. Observant. There weren't many mortals that Loki thought so kindly of.
"Demon?!" he asked, his eyebrows arching. A smile crept over his features and he let out a laugh. "No... no. I am no Demon" he noted with a slight shake of his head, a coy smile lingering on his lips, laughter lurking in his dimples. How did this man not know who he was? Even Angela knew who he was, even she had heard tales of the Norse Gods. Most knew who he was, or had heard of him, so why had this strange little man not? Or did he perhaps think that he was simply naming himself after the God of Mischief? Perhaps that was the case.
"I am Loki of Asgard. Son of Odin" he smiled. And with those words, his form suddenly changed. In a brief moment, in a shift of light and shadow, he was someone else entirely. Instead of the tall and skinny Loki that had been sitting there before, there now sat a old man with a patch over one eye. Once more, he smiled, a twinkle in his one good eye, and changed form again.
"Or how is this?" he asked. This time his hair was long and golden, his features chiselled and handsome, his form far more muscular and his clothing more fit for battle. "No, that won't do... how about something more familiar?" he asked before shifting form again.
This time he changed into a woman. She was rather plain looking, but dressed all in pink, from her shoes, to the paint on her fingernails. Loki had seen her picture sitting nearby when he walked in. It was all he really had to work with. His new feminine form smiled and turned a hand to gesture upwards and yet at her new form, as if to bring attention to it.
"Does this answer your question? There was no edit. I was the one you saw. Those were my memories. It was me in the beginning and me at the end" he added. "Perhaps it was fate that brought me here or something else entirely" he shrugged. "Others were brought here by other means. Through false hopes and promises. Which brought you here?" he asked, his form shifting back to his own, natural appearance.
