Ellis was surprised and amazed at what she said. Luck, being her power? How does that work? Those questions, along with much, much more raced in his head, and he knew, the only way to understand if he sees it in action. "I could show you if you wanted, but you have to show me yours." she said. Taken out of context, that sentence could very well knock Ellis out.
"Sure. You already saw it, though." Ellis said, as he pointed to Mister. Mister then flickered, and blurred, and later, he was gone, and a cute, white rabbit half the size of Mister replaced him. "So yeah.. My power is illusion." he continued. He snapped his fingers, and the rabbit disappeared. Then, he beckoned Marie to look outside, where Ellis saw a copy of himself, waving at Marie.
"So, show me yours?" He said, genuinely curious of her power over luck.
