Determination entered the gaze of his opponent, revelation mixed within.
Something had clicked, Thesh could taste it on the air between them, and despite not knowing what exactly it was he could not help but feel a momentary swell of pride at knowing he'd had a hand in it. Would it be his own undoing? Who knew. In his present state, at this point in time, Thesh was not playing the power game. He would not break down others just so he could rise. It did not need to be that way. Not in his mind.
Chains broke around him, and he brought his saber forth to lash through the air as Quintus neared him and blade met blade. Thesh's action was not so fast as it had been, the angle of his defense improper, and he received a stinging burn to the forehead for his folly.
He could feel the waves through the Force as Quintus pushed within it, and braced against the unseen strike. Chaos swelled around them both as each clashed with the other time and time again, but the man before him had opened flood gates Thesh had done his best to keep closed that day, he had brought the Force to a lightsaber duel and the temptation to return that act in kind was unbearable.
So he drew upon it, igniting his core with the chaos not only brought between them but all within that room. It was the wilds once more, despite the crafted structure they stood within, and Quintus was just another beasty entering the fray.
Back and forth on dancing feet Thesh moved, ever in motion so as to build up momentum while the two exchanged blows; then he truly lunged in full commitment, and as he did so he brought up his free hand as conduit and pulled Quintus into the path of his blade through the Force.
