Been watching Lionel lately. I share some of his political views and differ on some, but from the left tongue perspective there is a great deal of movement on his right side (my left visual field) of his face that is more prominent than the left side. However he does use both sides expressively. Keeping the video on pause and using the arrow to jump on the timeline there are significant differences. I believe my instinctive way to see his face is to really see only the right side and relate to it with my dominant right side.

It's a fun face to watch no matter, but he needs a better set
