The Professor is apparently trying to create his own Batfamily at this point, it seems. He has his adopted daughter Flora; he has this son Alfendi; now he has this daughter Katrielle. Who is Alfendi's mother? Who is Katrielle's mother? Are they full siblings or do they have different mothers? Are they adopted like Flora? Will either Flora or Alfendi be acknowledged in this "Lady Layton" series as being her brother and sister?
And for that matter, why does Level-5 keep acting like Flora doesn't exist? They already gave the Professor a daughter, but now they're bringing in this Katrielle character when they could just as easily have made the "Lady Layton" series about Flora.
