[ In a break from the 'everyone texts forever' show, here's a voice message—a deliberate choice, because he doesn't want there to be any room for thinking he's entertained instead of very very sorry. ]

Kate? Hello. I'm very sorry, but I think someone—Johanna, maybe?—accidentally connected with me somehow while she was with you. Not for very long. [ White lies? ] I wouldn't even say anything, but I thought you should know in case it wasn't only me. Maybe she could learn not to do that anymore.

Sorry.

[ Also sorry for telling Sirius, kind of. You know how it is. ]
