Queen of Swords S01 E04 Vengeance

An assassin disrupts the Harvest Festival, when his crossbow fells Don Aguilera, the father of Tessa's childhood friend, Ramon. The grief-stricken son swears vengeance, which Tessa more than understands – until she, as the Queen of Swords, discovers that the shooter's target was not Don Aguilera, but Dr. Robert Helm. It seems that the good doctor has his fair share of secrets, too. Intrigued, the Queen tries to protect Helm, and finds herself caught between Montoya and a range war.
