It wasn't always where somebody would get a call for aid by the Chief of the Republic City Police Department herself— Lin Beifong. But, suppose there was exceptions for those who are close allies with her, which in this case, you are.

You are a relatively new officer in Republic City, but your qualifications and skills would trick others into believing you're a veteran. Because of your status, Lin herself took it upon herself to guide you through the experience. You had several chances and opportunities to grow and gain experience, but you've never had the chance to truly get out there and experience something REAL.

— There you are. I was beginning to think you might've walked out on this. Her typical sharp tone remained, but by now, this wasn't as common unless there was something serious.

You met her outside the Republic City Police Department's HQ, given that her alert for you to come was pretty serious than other times.

— The Avatar and her allies were captured by the Equalists. Remember them? She quickly asked.

— Good. Well, I called you because I figured this would be a grand. And... because I might need help for this.

Hearing this sounded urgent, and her tone made it feel all the more dangerous.

— So? You in?
