Reyin would have been offended if he had known the bard had pegged him as just some sort of average, run of the mill swordsman, and any sort of expert swordsman would have been offended at the notion of Reyin having anything in common with them.
A five foot long metal stick wasn't exactly easy to hide, no matter how baggy the clothing was, and the fact that the staff still had to form gave Reyin plenty of time to react. A few seconds was enough time for Reyin, from a complete stop, to burst into a run and be fifteen, perhaps even twenty yards away. Reyin wasn't going to run away, that would be silly, but the reference holds just as well for, say, dodging.
For the staff to be of any use, it would have to have been thrust forward before Reyin had even begun his thrust. After all, the staff's longer range would be useless if Reyin was within range and striking first. That wasn't to say Reyin still wasn't in the motion of preparing his stab, though. The sword was just in the process of being thrust forward when he caught notice of the staff forming.
"Shi-!"
Stab abandoned, Reyin took a short step to the right with his right foot and spun his sword around his middle and index finger, reaffirming his grip only when the point of the sword was now aimed behind Reyin, the hilt now pointing towards Saphen.
Planting on his right foot, Reyin both moved and turned his body enough so that the end of the staff slammed into nothing but air. And before the simple weapon could be brought down or back to a ready position, Reyin's left hand moved up and curled around the staff, with the thumb pointing down towards the ground to assure a stronger grip.
What happened next was quick. Reyin pulled on the staff, practically using the weapon as a support to hold himself upright because his left foot was no longer on the ground providing balance. His right knee was bent and the only planted foot was square on the ground, but the arch of Reyin's back put a lot of his weight behind him, where nothing waited to support the young swordsman.
Reyin was leaning backwards as he pulled, aiming to drag Saphen forward and gut-first into the oncoming left foot. Meanwhile, with his right hand, Reyin practically threw a vicious hook across his chest. The desired effect was soon obvious. With the left foot, Reyin was hoping to double Saphen over as his lungs were exhausted of their air, and with the right hand Reyin was hoping to slam the pommel of his sword square into Saphen's left temple.
