It was indeed sad, but it really hit me when I read JMS's post about Andreas Katsulas' passing on the front page of ISN News, a URL that was sent to SoCalBrowncoats. I got pretty choked up reading it. The world has lost a good man and a wonderful actor, and JMS' obituary is a beautiful tribute to the man as well as the actor.
There's also a video tribute (larger version, 92Mb).
