Connor had not anticipated that Birdie became the person in charge of Rockefeller for the sole purpose of avenging her own brother.
He knew how dangerous she was.
So he currently had no way to determine whether what she had just said was true or false.
However, he knew that it was unlikely that she was lying about Zeno killing her brother because she knew about his abilities. If it were a lie, Connor could easily investigate and find out.
"Mr. Connor, I can help you with the first two things, but as for the third thing you mentioned, I can agree to it as long as you can help me seek revenge!" Birdie said, adding, "After all, I joined Rockefeller solely to avenge my brother. Whether I work for you or Rockefeller, it doesn't make any difference to me as long as I can get revenge!"
