I have no desire to tempt fate and attend Bellatrix's dueling practice considering that the wedding will be six hours later. We really do not need the other guests suspicious if the Death Eaters arrive limping or favoring appendages.
As such, I have no intention of attending practice Saturday. I have been training sporadically with Severus & Alecto to keep fresh. So it is not as if I have been doing nothing in the interim period since our last.
