I noticed that too.
As I watched Chad I also noticed another peculiar behavior or character trait. I'm not quite sure how to word it, but it looked like he had taken upon himself the role of author (I do realize he is one). What I mean by that is he seemed to have a deep fascination with the proceedings of court, paying attention to every little detail and word that was said. Even though he sat stone cold through most of the hearing, betraying little emotion, there was an intense look of interest and even thrill with the whole courtroom experience. It's as if he wasn't there as a defendant, but rather as an author witnessing the courtroom drama, soaking it in and gathering source material for his next book. And every now and then he'd suddenly seem to realize what he was actually there for, as the defendant in a criminal trial, and his countenance would change - he'd suddenly look around a little nervously/sheepishly, trying hard not to betray any emotions. But inevitably he would soon be caught up in the author role again, with a slight smile on his face as he examined the exhibits being shown to his attorney, etc. It seemed to me like he was a mystery thriller author working on his next best selling novel. Or else a calculating character within such a book trying to plan and scheme his way out of a predicament and finding joy and thrill in trying to outwit a cunning adversary. Either way I found his demeanor rather odd and baffling.
Does that make sense? Did anyone else pick up on that?
