"You have since then explained their deal in more detail."

I sure have.
I'm gonna go explain to them that you're here, I think.  Sound good?

"Sure." He will very much not look at the book.

The jacket glides away from the desk, then descends to the floor and piles upon it.  It stays like that for several minutes.

Oh, probably the jacket can't go through the floor.

Eventually it gets picked up again—seemingly from above?  It's hard to say—and shrugs itself onto something.

We're here.

"Hello, Mr. and Mrs. Frazier, I'm Cam, Charlie Swan's son."

The jacket has a silent conversation facing towards the middle of the room.

Melody Anne: Pleased to meet you.
David: Hello.

Handwriting is different and everything?

Nope, it's the same.  The jacket's the one writing it.

"- you two can't hold a pen even on Halloween?"

Conversation conversation.  The jacket goes and sits on the side of the bed.

The pen budges.  Rolls, a little bit.  Budge.  Budge budge.  Gets a bit of angle up, falls back down.  —There it is, up and putting ink to page, a wavy squiggle—it falls again, onto the floor this time.

The jacket returns.

J:  They'd prefer I do it.

"Okay. Well, if there's anything you've wanted to catch up on from the world of the living, or want known to said living from the land of the dead, here I am."

J:  They're thinking about it.  If there's any obviously supernatural noises or moving objects in the room that's them disapproving of something I've written.  If we picked a specific thing there's a chance I could just hold it still but I can't do that for everything in here.
Or if you get chilled all of a sudden.

"Is that likely to be as heavy-duty as when I touched the book, or...?"

I would guess not but I might be wrong.  Th

 

MA:  We won't do it unless the other options don't work.
J:  Which they will, because I won't try and stop them, and also hope to not get to that point in the first place.
D:  It's a precaution.
MA:  More for his s your sake than ours.

"Good to know..."

Was it that bad?

A 'J:' appears belatedly at the front.

"It's just an interesting balance between - considerations, is all."

MA:  It's only sensible to be a little worried about the possibility of deception, in this case!  So it's polite to put you at ease with the knowledge that none's happening at any given moment.

"I appreciate the sentiment."

D: How are the Seahawks doing this season?

"I have absolutely no idea, I don't sports. I can ask Charlie."

MA:  Don't you worry about it.  We're not from the area; he was just trying to be polite.
D:  We've lived here longer than anywhere else since Jeremy was born.
MA:  No, we've been here longer than [that].  It doesn't count if you can't watch a game.

"...then I will not ask Charlie about the Seahawks if that's all the same to you."
