Willow sits up, "Oh.. I can change the way light bounces off things in order to change colors or create illusions," she says, happy to have someone interested in her, "A lot of the color changes that happens to me are just subconscious, like fitting my mood and stuff, but I've learnt to control it too." She points to the wall where a 'wet floor' sign stands, "There's a person over there. He passed out yesterday and we didn't really know what to do with him, so I just made it so no one can see him until he wakes up." 
Willow then stopped, half embarrassed at the tumble of words that had spilled out of her. [@CandiBarr]
