Thor lifted his own journal to show them the half-filled pages, careful not to show any of his and Loki's correspondence. "You simply write. I asked that these not be connected to Asgard since I am sure you do not wish to see my mother's notes to me." He smiled sheepishly. "Though if you truly wish, I think I can figure out how... maybe." Or Loki could, but Thor doubted he would tell them that.
"As far as private messages, well, Loki and I just addressed it to each other. That seems to work." He shrugged and glanced to Tony. "I have quite a few, but the others are in case yours gets damaged... Unless you have someone else you wish to give one to?" And, despite the man's fatal wound, Thor also had one for the good Son of Coul. The man had always been kind to him, even while he was captive, and he held out hope.
