A lot of guests are at Severide and Kidd's wedding, Casey was best man and Brett was maid of honor.

Severide, Casey and Brett were all suited up for the wedding when everyone stood up and Boden walked Kidd down the aisle.

Unexpected guests like Cruz's brother Leon and Captain Patterson were at the wedding in fact Patterson was the officiant.

Dearly beloved, we are gathered here today to celebrate this man and this woman in holy matrimony, if anyone has a reason why these two shouldn't wed, speak now or forever hold your peace, Patterson says out loud.

Good, you two have written your own vows I believe, Kelly, you begin, Patterson says to him.

Stella, from the moment you first stepped through the doors of Firehouse 51, I was deeply in love with you, every second of it, and I couldn't wait for the next day, then the next, then the next because I get to spend it with you, I love you, Kelly says to her.

Stella, Patterson says to her.

Kelly, from the moment we met, I was impressed by the man that you were, the man that you are now, and the man that you will be in the future for the rest of my life, I will cherish you, for better, for worse, in sickness, in health, every day, Stella says to them.

All right, now for the main event, Kelly, do you take Stella to be your lawfully wedded wife, to have and to hold, in sickness and in health, for better or for worse, till death do you part, Patterson asks him.

I do, Kelly says.

Hey, Dallas, can you stop the wedding, a familiar voice to Severide says.

What are you doing here, Shay, thought you were dead, Boden asks her.

I was in a coma, got out last month, thought I would surprise you, Shay tells him.

This is amazing, a miracle, Shay, these are my fiance Stella Kidd and Captain Dallas Patterson, and maid of honor Sylvie Brett, who actually replaced you on 61, Kelly says to her.

Stella, Patterson, Leslie Shay, my former best friend and co-worker, Kelly says to them.

Nice to meet you, Stella says to her.

Same here, Shay says to her.

Carry on, Patterson, Kelly asks him.

Stella, do you take Kelly to be your lawfully wedded husband, to have and to hold, in sickness and in health, for better or for worse, till death do you part, Patterson asks her.

I do, Stella says.

By the power vested in me by the magnificent city of Chicago, I now pronounce you husband and wife, you may kiss the bride, Patterson says to them.

Hey, why didn't you tell me about the coma earlier, Kelly asks Shay.

Because, I didn't want you to lose focus on your wedding, Shay tells him.

Shay, if you told me this earlier, I would've rushed to the doctor's office to watch you wake up, Kelly tells her.

Congratulations, and good luck, Shay tells him.

You're a lucky woman just to have him, Shay tells Stella./pre
