Cho...honestly didn't have a plan when she'd written George, which was a different thing for her. She usually planned things out and put them together before executing them. Why she'd called for George, she didn't have an exact explanation for either outside of 'he'll have paints and will probably enjoy whatever I come up with'. With neon orange paint involved, it was likely to be childish enough in nature.
By the time that she heard knocking on the door, she'd formulated something of a plan, so she went to open the door. "Hello, Weaselcakes!" It was cheerful enough, she thought...even if she'd been thrown off a bit because of Voldemort's sudden arrival. She'd told Cedric she'd hurt anyone that tried to hurt him and she'd meant it. But that wasn't what now was about...entirely.
"I thought we needed some artwork to hang around that wasn't crayon drawings and...what is better than ridiculous paintings of whatever. I don't even know. The sun? Hideous, neon orange animals? I don't know. Something. I needed a distraction, I guess. And to stop staring at things for work. My eyes hurt." She shrugged slightly. "Unless we want to turn a room into some strange painted monstrosity...but paintings on paper are probably better."
