He already knew from the beginning that something is fishy. The current Annelier's manner after waking up is very different from the original Annelier. So he tried to messing around and give her kinky command, in hope that he can get some information, whether she's a spy or something. Turn out she's not anything of sort, and he kinda like the current innocent Annelier in the end.
