One full explanation (and dessert) later.
Bianca: It’s a good thing you told me to become Patrick’s Master . . . I feel like this would be even weirder if he was yours now.
Patrick: There’s so much I didn’t see . . . and now I can’t unsee it.
Bianca: Only Miranda knows, right?
Sparrow: Yeah, she hasn’t told her dad about it.
Bianca: And have you told your mom?
. . . Okay, you should probably call her.
Sparrow: No — not call. I have a better idea.
Sharon (thinking): A letter! . . . from Sparrow? I wonder if it’s to tell me her email’s been hacked.
Anyone got any idea why a letter is the way she chose?
I’m willing to bet there’s a piece of paper in that envelope that’s not exactly in English.
After all, an in-person discussion would be a much better way to talk about this, and the teleportation sigil has to be at both ends of the path.
