The reaction was exactly as Lelouch intended. Rage. This man had a barely checked hot temper, marked with a brilliant tactical mind that stood on the same level as his own. A rare thing, but a weakness is a weakness and he fell right into his own weakness just now. At the moment he’s thinking “this boy’s Stand can’t attack.” But he was wrong. Critically wrong in a way he could never predict. He inhaled, the “ripple energy” coursed through his veins into the hand projecting his Stand -

Then entirely changed course and flowed out through his feet, into the rug he was standing on which suddenly and harshly pulled out from under him.

Of course, a trip like that wouldn’t keep someone like Joseph down for long. It was merely a distraction while Lelouch let the tension out of his muscles, and used the very slight give to climb out of the grip of these thorny vines. He was out on the floor, panting a little due to exertion.

“Oh! My! God!,” Joseph said, staring around at the again seemingly empty room. “That was an interesting trick. You only said that to make me angry so I’d try to hurt you. Nice work!”

“That’s right. I lied and you completely fell for it,” Lelouch replied, extending his open palm in front of his face. “It was easy to play on your fears, then change the ‘path of least resistance’ by making parts of your body invisible to Ripple energy. However, in the interest of fair play I should warn you that I can also make it work the other way around!”
