An I don't own Chicago pd or any of its amazing characters :( this is just a little one shot I wrote when I couldn't sleep . Doesn't have much plot but any reviews would be appreciated :)

She remembered the first time they did this. Helped each other suit up. The first time she felt his warm hands gently press her shoulder almost hug her side. She remembered it very very well.

It had been after an incredibly difficult case that had meant almost three days with no sleep. They stood suiting up when her hair got caught in her vest, the Velcro latching on to it tightly and simply refusing to let go. Jay had helped her untangle herself and ignored how she blushed slightly, merely joking at how she should cut her hair like his so she wouldn't have such a problem.

She had punched him jokily in return and was about to make a witty response when Voight called them over for a final brief.

It had carried from then onwards. She would hold her hair back and he would strap her up no questions, no comments, just partners being partners. It wasn't until a month into their new routine that she got to repay the favour.

He had taken down a suspect badly and got in a fight in consequence. After a long tumble and many well placed punches he had managed to deliver a swift upercut to the head and knocked the guy out...though not without injury. He never stated it directly but after working with him for so long, after having his back in so many busts Erin knew how he moved and she could tell that his arm was giving him trouble.

He performed bad ass as usual in the field and it didn't stop him complaining about not driving but she had seen how he put more weight on his left arm when he aimed, favoured it to open the door or reach for a coffee cup so she knew he would have trouble putting on the vest. As a result when they where told to suit up and after he had helped her she avoided eye contact and took the vest out of his hands and strapped it on, before whispering "that's why you have back up" in his ear.

Six months later and here she stood holding back her hair as he pressed the final strap. For possibly the final time. It felt wrong, so wrong that such a tradition should come to an end, that such a partnership should be stopped , that such a door of opportunity should be shut. But there was no going to back now. The task force meant stopping the crime instead of cleaning up after everyone's mess and after doing so her whole life , she was desperate for this chance.

She had always been one for not letting anyone get in her way or hold her back, (even if they were extremely handsome, smart, funny etc. etc.) and she wasn't about to change that. She wanted to be free to make the changes that the world needed, to be strong and independent and to keep the city safe. So if that meant leaving behind possibly the best man on the planet then she would have to do it. No matter how much if hurt. No matter if he lead the way to the car casting his usual longing glance to the drivers side, his cute smirk on his face, caused her stomach to jump. She had to do it. She had to leave.

But would that really mean forever?
