"James did over the summer and Michael said he was being very rude and should drop it and Timothy backed him."
"I mean, if Timothy were aware Michael was going around having flings with Muggles without protection he would make him stop, and then he'd track down the girls, and Michael'd have found out about Catherine before she was already two months old. He probably wouldn't literally intervene."
