Kodi died.
He blew up the last two sorcerers.
Tadeusz's eyes were about to split with rage.
He felt it was his own inadequacy that forced Kodi and his squad to engage in a fight to the death, coming up to mop up the situation.
They coordinated a flanking maneuver and launched an attack as agreed, the enemy successfully completed their mission, while his own side was obstructed. All five sorcerers were dealt with by Kodi's squad...
What am I really doing?
Objectively, Tadeusz certainly played a role in creating diversions and opportunities, and he killed many of the armed rioters protecting those sorcerers. It can't be said that he was completely ineffective, in fact, quite the contrary.
However, looking over at Kodi's situation, the contrast made the gap apparent.
He wished he could rush forward like Kodi did, even if it meant dying, just to take down a few more enemies. Only then could he quell the burning frustration in his heart.
