The Seven Deadly Sins Season 1 Episode 4

Diane throws Gilthunder out of the forest and decides to accompany Meliodas, Elizabeth and Hawk on their travels. Their next stop is Baste Dungeon, where Ban, the bearer of the Fox’s Sin of Greed, has been imprisoned for five years. However, Meliodas collapses suddenly from his injury and they decide to stop at Dalmary Town, letting a doctor named Dana treat him with medicine. There, Diane and Elizabeth both show care for Meliodas, but display envy towards each other due to their opposites in strength and size, with Diane ultimately deciding to leave to find Ban herself. Unbeknownst to them, Dalmary Town is currently under the rule of the Weird Fangs, a unit in the Holy Knights, who are determined to kill Meliodas and Diane, and capture Elizabeth. Dana also unexpectedly reveals to a shocked Elizabeth that the supposed medicine he administered is a deadly poison, while Golgius, a member of Weird Fangs, appears out of the blue to escort her back to the Kingdom of Liones.
