See, I want to say that Sarah is writing this, but I imagine Elliot would just be his regular self if she were the one typing?

Grace, meanwhile, would write something completely innocent that others would interpret as being anything but.

One could argue Ashley, but Ashley, whether intentionally or not, tends to include a self insert of some sort. Granted, that doesn't HAVE to be the case, but I can't help but think she'd write herself in place of Tedd or something.

Susan could imagine this happening, but she's not actually big of writing fiction? I'm sure that will never change or be ironic somehow.

If Tedd were writing this, it would be WAY less subtle.

I don't know. We're running out of suspects. Perhaps I actually am writing this myself?
