The problem arose; Wu is not an ordinary Chinese restaurant owner.
His background cannot withstand scrutiny.
Especially not from a colossal figure like the Mayor of New York!
Once they found out that the girl nearly accosted by the pajama man at the party, her father turned out to have a secretly hidden identity, either as a ruthless assassin or something else...
If you're the mayor, wouldn't you suspect that the box was most likely stolen by this guy?
Moreover, once Wu's hidden identity is uncovered, leaving aside the mayor's issues, his own background would cause him many problems.
So, Wu's solution was simple.
Eliminate the person.
The mayor would investigate the box; he would uncover his background.
If there was no mayor in this world, then there'd be no problem.
Of course, while he's at it, also get rid of the pajama man who nearly accosted his daughter.
