I don't have the time to look it up, but if Fritz did hear about it at the time, it might have come up in his correspondance with Wilhelmine during those same months. Especially since I seem to recall there were several snippy comments about the Duchess from him during that time anyway (aproposes whether or not she should have custody of her son Carl Eugen, Wilhelmine's future son-in-law) and Wilhelmine wasn't a fan of the woman, either, though her own mixed feelings came more into play after her daughter's marriage, not before.
