It's not his footwork that continues to give him away; Loghain might disdain the Orlesian chevaliers, but he'll acknowledge that whoever instructed Nathaniel taught him well. It's the two-handed grip on the sword, which does not pair well with his stance or his other movements. To make those movements work well, he needs to heft a bigger blade, one that will naturally keep Loghain at a greater distance to avoid the force of its strike.

As it is, when Nathaniel stabs for his middle, Loghain can predict his angle of approach again. He deflects the blow and, same as before, forcefully pushes him off with the practice blade. This time, he doesn't go in for another blow.

"Can't hold it with one hand?" he asks, nodding to the sword.
