Zacharias wouldn't have known how to let someone in even if he wanted to, whether or not he needed help. Which, he reasoned, he didn't. His father was not like that husband Ernie mentioned. His father was not a killer. His father was not abusive. His father was just strict and liked things to be a certain way. And Zacharias had a way of pushing his buttons. He'd always been able to do that. And it didn't seem to be just his father's buttons he could push, but he decided to push that all out of his mind for now, glancing down at his wrist and the fading light.
"I'm fine, thank you," he said of the offer for food. "But if I'm not interrupting, I could stay for a game of chess or something." He wasn't the best at chess by any means, but he at least wasn't an upset fifth year holding a grudge anymore. If he lost, he could lose with some dignity, especially since Ernie could have turned him away. "That is, if you're not set on getting back to your research," he said, mentally deciding to do a bit of his own to keep an eye out for Ernie's safety. In his mind, it was the least he could do for all the help Ernie had given him over the years.
