Because Sion's life is a mess.... he's not going to be getting his letter on time. He'll be getting something that would have been helpful a month or two ago because why not.

Keep Ferris home. Let Luke do his job. Because I can't, and he can't either.

However it is going to be handwritten, and thus look like this, so he will BS that it is something else.

And probably be noticably more down on himself after. Welp.
