Mary chuckled at Lucifer. He had a way of making children like him that was beyond her - he treated them like small adults in a very unironic way that she admired. Esther reacted to it well, grinning and shaking her head.
"I'm three, silly!" She held up three fingers, as if to illustrate the point, in case Lucifer wasn't just playing and was actually mentally deficient.
Mary sat with her legs underneath her as she ate and shrugged at Lucifer's comment. "I don't know. Do you have a friend you need set up?" She giggled and hummed in pleasure as she nibbled on a pepperoni.
