Nothing, really. Just going to meet an old...frienemy is a good word, I think. Frienemy. He wants to talk about something, and judging by the fact that he said please I'm willing to bet either: A.) This is real. The fact that he said please to me, really any of us Animorphs, implies he's serious about this and not plotting something because I'm pretty sure he wouldn't be able to say please to us even for a scheme. B.) He is expecting me to come to conclusion A, and is using it to his advantage.
B results in pretty circular logic. Don't worry, I'm bringing back-up, and yes you can come if you want, I wouldn't even try to argue it. But out of courtesy to him - I'm giving him this courtesy because he's been pretty chill since getting here and hasn't tried to fuck with any of us - anyone that comes with me needs to stay out of sight.
