Loki nodded at the 'need' to know. "And yet I shall treat him as a stranger barring any prior meeting of him." He easily saw what Puck was doing and why. It could be very useful.

A thought struck him though. "Until you regain your own magic, should you need it--I specialize in illusions and manipulation thereof, along with conjuration as you've seen. It wouldn't be hard to make an illusion of your chosen persona if you need it sooner. Nor would it be difficult for me to change either."

Standing, Loki grinned and let a wash of green flow over him. Where he'd stood before was now a soldier. On par height-wise with Loki, but broader and with clearly different features. His manner of standing and voice were even changed. "Something like this. One of Thor's friends, a very righteous defender of truth, justice, all that."
