It seems to me that Sigurd won't be able to put a lot power into his strike from his current position to actually muster a grievous wound; perhaps, an inch deep into flesh at most, if not less, since he is missing a lot of torque from the legs, cannot put a lot of weight behind his arm in general and has very little wind up space as well. 

If that stands true, Gigue can just shrug it off and stick to his original plan, since it would work regardless in that turn of events.
