Arcadius, our second puppet emperor. Judge him against most, then he won't do well, but how does he compare to Valentinian II? Is he as useless? Does he have any redeeming features?
But let's be honest. No one is going to remember this as the Arcadius episode. This will always be the episode where Rob tells Jamie, in detail, how the Romans created their Eunuchs. Never before has a recording session been spent with as much time with crossed legs.
