Chicago P.D. my sister My problem

Chicago doesn't give second chances.
I learned that the hard way working under Hank Voight in Intelligence. You either survive this job... or it takes something from you.
Usually both.
I've spent years fighting to keep this city under control. Keeping my team alive. Keeping the people I care about out of the line of fire.
But I never planned for this.
My sister walking into my unit.
Bethann Halstead.
She says she's ready. Says she's not the same kid I used to look out for. That she can handle the cases, the danger, the pressure that comes with this job.
She's wrong.
Because Intelligence isn't just another unit. It's where things get messy. Where the lines blur. Where good cops start making bad decisions just to get the job done.
And now she's standing right in the middle of it.
Working alongside officers like Kim Burgess, Adam Ruzek, Kevin Atwater, and Dante Torres-people I trust with my life.
But trusting them with hers?
That's different.
And the worst part?
She's good.
Too good.
Voight sees it. The team sees it. Even I can see it... no matter how much I don't want to.
Because the deeper she gets into this job, the more I see it happening.
She's becoming one of us.
And in this unit, that's not always a good thing.
Because in Chicago...
you don't just fight the bad guys.
Sometimes, you become something you don't recognize.
And I don't know if I can stop that from happening to her.
