Main difference here:

Episode 2 – they catch him off guard
Episode 3 – he catches them off guard

The whole fight this time he had the high ground and fought on territory he already knew, so it only makes sense that he won.

Full set of armor = Ass kicked

Damaged clothes = On par

Almost naked = Better than them

Almost naked with severe blood loss, after living in a cave possibly for weeks in the freezing cold = Barely any effort required to kill them all
