Season 3: So will Uhtred bed the witch?
Seems to be the biggest existential question that sets up the rest of Season 3 after EP1.
With her accurately predicting the demise of his wife (who really expected his wife to survive anyway? That would deprive Uhtred of future love interests and a consistent feature of the show) appears to be setting up discord in his own ranks by those prone to superstition who think he's been cursed by the witch.
Of course Uhtred will utilize reason and logic to provide empirical clarity in order to ultimately prove the witch is a fraud. That's my forecast for Season 3.
