S1·E24 The Choice

Camelot's army sets sail for Thule at the beginning of a violent storm season. While preparing to reclaim his kingdom from Sinnin, Valiant faces the startling realization that he cannot abandon his people to become a Knight of the Round Table. He has always assumed that his journey to Camelot was ordained by Fate, but now he must choose for himself where he is ultimately to spend his life. A devastating Viking attack then forces the prince to make an immediate decision regarding the campaign's - and his own - future.
