Peter was always very affectionate. Leeloo discovered long ago that she liked it very much. She also felt that there was something she was missing -- something integral in the way he acted around her that she herself coudln't give back to him. But she very much liked to be around him, and she liked his heart. He was a good person. She tried very hard to be what he needed.
"I want to see your apartment," she answered easily, with a smile. The explanation he'd been giving her of the City and the place they'd arrived was borderlining on impossible - but Leeloo knew that there was more in the universe than what most people understood. It wasn't wholly outside possibility.
Besides, she wanted to get to know Peter better, and she already knew that one could learn quite a lot about people by looking at where they lived. She laced her fingers in with Peter's and nodded to underline her decision. His apartment would be good to see.
