Zathras has never watched Blake 7.
He will resolve this paradox.
skip the first episode of b7, you can watch it after you watch the rest of the episodes if you want, but it is super slow and not really relevant to the rest of the series.
I can summarize it in a few words
Blake was the leader of the resistance against federation, he was a threat so he was framed for child diddling, and sentenced to a penal colony. I think the only point was to show the federation was evil, and corrupt while Blake was good.

Have you seen the animated B5 movie?
I loved it although the animation style took a little getting used to.
