Barty wanted Evan. Usually that meant Barty had Evan, took Evan. Right then. None of this restraint stuff that was so hard. Barty was practically bouncing, so impatient he was too leave, to get Evan to that lift, and Barty didn't care right then if anyone else was in the lift, he was having Evan then, and no one was going to stop him.
"Healthier than a horse," Barty commented with a laugh, "I think it helps that she hasn't been punished much in fifteen years, increases the life span I guess." Barty didn't care about Winky at that moment, didn't care about house elf life spans. But he had to do something so as not to fuck Evan right then.
