The cult's leader blocked the [Wind Slash], but he was pushed back several meters. Because of the husband's attacks, the cult's leader had to stop fleeing.
Like what he did previously with the cleric, the thief only glanced back and kept fleeing, ignoring the cult's leader. In a dire situation, the desire to live was strong enough to sacrifice a comrade. Moreover, the three cult's founders only got together for their own benefits.
Seeing this, the husband kept on moving and chased the thief. Meanwhile, Auron was left to fight against the cult's leader. Several soldiers also stopped and helped Auron while the rest of the soldiers were chasing the thief and the husband.
Of course, the wife followed the husband on chasing the thief. However, there was already a cleric assigned to Auron's group.
