I am 90% sure James deserves the credit for this whole idea — I think he called or emailed and said “I want to do Law and Order but it’s Log and Order and one of the detectives is a log.”
From there, the thing kind of writes itself? I think the big play here is that the log is… just a log. It’s not a sentient log, and other than appearing various places, it doesn’t do anything. It’s just a log.
