Flashback

Severide: Stella Kidd, will you marry me?

Kidd: Hell yes!

Present day

Sloan: Severide, there's someone looking for you.

Severide heads out of his office to see a former fling.

Severide: I don't want to see you after you screwed up 51.

Hope: Kelly, I heard you're engaged, congratulations.

Severide: Thanks.

Hope: I'm sorry for screwing up everything with you and Stella.

Severide: Hope, you did something unforgivable.

Hope: Kelly, I'm not here to stay, I want you to come to Indiana with me.

Severide: Hell no!

Hope: Not good for me.

Brett: Severide, Hope can get angry, so watch out.

Severide: I know that.

Hope: Thanks for warning him, Sylvie.

Severide: I'm calling Patterson, try and get you out of Chicago.

Sloan: Well, well, well, a beloved figure is back at 51.

Boden: Peter Mills, welcome back to Chicago.

Mills: Thanks, Chief.

Herrmann: Hey, welcome back.

Brett: Mills, here to stay?

Mills: Yes. Spoke to my mom, she said that even without me, the resturant can do well.

Cruz: Do I hear the alarm or is Peter Mills back at 51.

Mills: It's really me.

Casey: Welcome back, Mills.

Mills: Heard you got promoted to Captain, congratulations.

Casey: Thanks.

Boden: Mills will be riding along with Squad 3, Sloan will be riding on calls on Police 51.

Sloan: Damn right.

Mills: I'm fully updated, everyone's been in touch, thank you for that.

Severide: Welcome back, Mills.

Sloan: Hope, Patterson's here, banishing time.

Patterson: This the girl?

Severide: That's the one.

Patterson: Hope Jacquinot, you did terror on Firehouse 51, including shredding a paycheck, putting in a transfer for a firefighter and forging a signature. Those things are unforgivable, Kelly told me everything. Hope, not only are you not welcome in the CFD, you're also not welcome in Chicago. Get out of here.

Hope: Unbelivable, calling in the big guns, Kelly. I will never forgive you!

Hope leaves in anger.

Patterson: Very bad woman. Glad you called me.

Severide: So am I.

The alarm goes off.

Radio: Engine 51, Truck 81, Squad 3, Ambulance 61, Battalion 25, structure fire.

Boden: Let's move!

Patterson: I'll see you there.

Sloan: Ride with me. Mills, you're with Squad.

Mills: Got it.

All units arrive.

Boden: 51, get a line in there.

Herrmann: Copy, Chief.

Boden: Truck, Squad, search, Ambo, triage.

Casey: Mouch, Gallo, set the aerial, Kidd, with me.

Severide: Cruz, with me, Tony, Capp, help Truck.

Patterson: Wise choices, Chief.

Boden: Thanks, Dallas.

Sloan: Mills, help me.

Mills: Got it.

Squad and Truck pull people out of the fire, then Brett and Violet check on them and ambulances take them to Med.

After the call

Sloan: Glad to have you back, Mills.

Mills: Glad to be back.

Severide: Amazing work.

Mills: Thanks. Congratulations on the engagement.

Severide: Thanks, man.

Patterson: Same thing from me.

Patterson leaves 51.

Mouch: I forgot to say. Welcome back, Mills.

Mills: Thanks, Mouch.

At the loft

Severide: A shock to see some old friends today.

Kidd: Yeah, what if someone comes back from the dead.

Severide: Impossible, but I would be shocked if someone like Shay appeared in front of me.

Kidd: Your Mills friend was a joy to see at 51.

Severide: Yeah, I'm glad he's here to stay.

Mills will be in all other chapters, Patterson will also appear throughout the story.
