This Sir? Dark Knight

This was how the world worked.

Although Batman and Black Cat had crippled a lot of New York hoodlums, they still respectfully called the two "sir" and "ma'am."

That was because the rumor was that whoever spoke ill of these two behind their backs might immediately get a visit from them.

Later, the rumor changed to whoever uttered these two names might be found by them.

Under the threat of permanent disability, the hoodlums would rather believe than not.

Thus, they never said these two names unless it was necessary.

Suddenly, one of the hoodlums came back to himself and pointed at Luke. "Who are you trying to fool? Bat… that sir died trying to save New York. Also, your eyes aren't right. Wait! You want to hook up with this b*tch, which is why you're trying to scare us, right?"

The three other hoodlums were stumped for a moment, before they looked enlightened and then relieved.
