The cliche of being able to fight a person blindfolded or with one arm behind his back may in fact actually apply in this instance, though it's not something Peter is eager to test against an Edmund with no evident code of honor in employment. As it is, watching the initial advance he gets the feeling that curse itself has muddled the other king of old so thoroughly that the aforementioned cliche wouldn't do here after all. His focus is all wrong, and that's a red flag if ever there was one with the Just.

He crosses the blades only to slide Rhindon down with angled force, locking against the other sword in an effort to draw them closer together, bringing his foot behind Edmund in the same breath. It's a basic matter of making him lose his footing and then keeping him down...and then getting him up to the house.

Very nearly Peter utters a sound of exasperation right then and there but refrains. One thing at a time.
