After a moment of silence, the captain says, "This mission is very dangerous, Katrina. Are you sure you're mentally prepared to take that risk?"
Going to a foreign country to catch a fugitive is a lot more different than traveling abroad for leisure. Nobody can predict what kind of situation they will face in Thailand. The only thing for certain is that it will be a very difficult task, and there's going to be a lot of danger.
The captain is worried that Katrina might not be able to overcome such difficulties. Besides being a girl, she has not been a policewoman long. She has not taken part in many big cases yet. Assigning her such a dangerous task might be too much.
Katrina nods furiously. "I can do it, Captain!"
She is capable of doing the same things that her male colleagues can do. Although their division of labor may be different, she also wants to do her part to help the team in catching criminals at large.
