River men in 'Cross of St.Ciricus'?
In this episode, the entire existence and meaning of those weird "river men"- who seem to be aquatic semi-humans that submerge beneath the water level in wait for an ambush, is never explained?
Were they simply supposed to be superhumans bent on loot? Were they based upon some forgotten legend?
Why wasn't it explained in the script, even a passing reference between Guisburne's mum and Tuck, or the others that fought them?
