The Illusions of good and evil
Well, he had promised Darcy fireworks so fireworks she would have. Perhaps not the sort she imagined, but nevertheless. Loki grinned and kept himself out of sight on the balcony of Stark Tower. Tony was away with his child for the moment,deep in the lower levels of the Tower--a perfect time to stir up a bit of trouble.
Taking a deep breath and ignoring the thrill in his veins, Loki wrapped his illusion around himself and stepped forward. The many polished surfaces showed sharp cut facial hair, a substantially shorter stature, and the clothes of Midgard. Putting a hand to his face, Loki smirked. JARVIS spoke suddenly, startling the god, "Sir? I'm reading your presence in two places within the Tower."
When Loki answered it was in the irritatingly familiar rough tones of Tony Stark. "I-It's fine. Nothing to be alarmed about." With a quick bolt of energy, he hoped to bewilder the machine enough to let him continue with his plans. The god felt his heart rate speed up in the silence that followed, then let out a controlled sigh of relief when the AI answered with a tone of hesitance and almost confusion, "...Yes sir."
Loki grinned widely, "Very good. I'll be visiting my fellow Avengers, do let them know I wish to speak with them, privately?"
