As far as I can tell, the commentary length is reduced to the three places where most of the talking is done: Newhome, Kittania, and the Common Ground.

I make the many models of a mutant individual. To make them I use vegetables, animals, and minerals. From robot bugs to zombie bears to many singing barnacles.

I remember when Kitt was fairly quiet last season and Central was the talkative one.
Hey wait a tick...
Chim, I think I'm being followed.
Hurry, I need somewhere to hide.
The Grounds were quiet too though back then. Now they're like the local hangout for all dem teenyboppers.

Actually, I'm super-duper happy over the shorty commentary.
