Light mused at himself as he looked at the black and white filth. Filth, that he lived in through this curse. He had been curious about changing the house to full color. Maybe, if he did something inside of it, it just might change to color. That would be a treat on it's own.
However, this was to help Riddle back. The young man waited leaning against the back of the couch. Light would try to be pleasant or something. Manipulative, seductive? Which would he want? Mindfuck. Hardly.
He grinned wide as he heard the knock on the door. Ah, so there he was just on time too. Light took short steps over towards the door and opened it up smiling wide at Riddle. "Good Evening, Mister Riddle. Do come in."
Light could easily pull off being nice it wasn't anything new to him. Acting, being someone different, it came with his job. The young man stepped out of the way for the other to come in. This would be most delightful to bring back a man such as Riddle. Maybe something good might come out of it.
