After moving out of Allen Apartment, Kallen had been living at the Pavarro Funeral Society, which was also the Pavaro Tribunal.
By the time the attention surrounding the "Qi He Case" died down and Vicolai wanted to take revenge, Kallen had already begun to distinguish himself.
Especially after Kallen emerged from the York City District selection and drew enormous attention, Vicolai would not dare risk taking revenge as long as Kallen continued to make his home at the Pavarro Funeral Society.
Then, as Kallen kept progressing, improving, and receiving more attention, Vicolai's desire to take revenge on this subordinate Inquisitor gradually became deeply buried.
Because it was not worth it.
Finding a way to engineer an accident on a mission and kill a low-ranking Inquisitor with few friends was not particularly difficult;
but killing Kallen... or making Kallen come home to find everyone under his roof dead without his investigating and retaliating would be very difficult.
If Kallen had not chosen to make his home at the Funeral Society, Mrs. Lake, Dora, and Doreen might already have been dead.
Yet Vicolai's reason for revenge was truly laughable.
He had assumed Mr. Pavaro was already dead and taken credit for Pavaro's accomplishments. Kallen had then appeared as "Pavaro" and made demands, forcing him to pay an additional 10,000 Order Vouchers and help raise his Inquisitor rank somewhat.
None of this amounted to anything for Vicolai or the Nadun Family, yet he believed his dignity had been violated and insisted on taking revenge and silencing them.
What Vicolai did not know was that, while he was waiting for the attention to die down before killing Pavaro's family, Kallen was spending that very same period waiting for the attention to die down before killing Vicolai;
at a stretch, this could count as meeting
