Mistakes [Jay Halstead & Will Halstead]

Description: Y/N and Jay are in a secret relationship. Will likes Y/N and makes a move on his brothers girl.

Y/N and Jay had been secretly dating for four months now, and it was going relatively well. They'd spend the night and most days off together, and have little dates at home. Which is what they'd done last night.

Y/N locks her apartment door and follows Jay into the hallway.

"Ready?" Jay asks. Y/N nods and they interlace their fingers before they start walking.

Jay walks Y/N to her car and they stand outside of it for a few seconds.

"Be careful today please. I don't need you showing up in the ED with a GSW."

"Can't make any promises, but I'll try my best." He chuckles then kisses her forehead. "You be careful too. Don't try to fight grown men if they are on steroids."

"Will do." Y/N laughs. She looks at her watch and sighs. This was her least favorite part of the day. "I'll see you later, ok?" Jay nods and gives her one last kiss before he opens her door for her and closes it once she gets in and starts the vehicle. He doesn't make his way to his vehicle until she's made it out of the parking lot.

Y/N and Will were working on a young boy who'd been brought in, obviously assaulted. They'd called for the police to come to the hospital, but then they got dragged into questioning from the head of the hospital.

They'd finally made it into the break room for they're lunch when Y/N caught Will staring at her.

"You ok Halstead?" She asks as she sits down next to him.

"Yeah." He clears his throat and looks away. "Just thinking about some things."

"What things? I could probably help." Y/N offers and sits her lunch on the coffee table.

"Well. I uh-." He hesitates. "There's this girl I like. I've liked her for a while now, but I don't know much about her, like if she's single, because she tends to like having her business broadcasted to the whole city of Chicago." He pauses. "She sort of acts like she might feel the same way, but I'm not sure if it's just how it seems to me."

Y/N thinks for a minute.

"I could tell him how I found out Jay liked me. I mean telling one person about us wouldn't be terrible, besides, he's his brother."

"Well, you could try making a move on her, but a subtle one, you know? So it's like if she responds well to it, she most definitely is attracted to you, but if not, she'll think of it as a friendly gesture." Y/N explains. Will nods and they sit there for a few moments in silence before Y/N starts to speak again. "I actually want to tell you something. I'm-." She gets cut off by Will smashing his lips onto hers. Y/N squeaks and jumps up from the couch. She covers her mouth with her hand. "-Dating your brother!" She finishes.

Jay has seen it all. He was the Detective sent to get information from the boy, and Maggie had told him where both you and Will were.

Well, he didn't see it all. Just the part that makes it look like Y/N kissed his brother.

For the rest of the day, Y/N didn't hear anything from Jay, and when she went to his place that evening, she didn't expect grumpy Jay.

"Hey, what's wrong?" Y/N asks as she sees Jay's grumpy demeanor.

"You should know." He states coldly.

"Ok?" She drags.

Had he seen what happened?

"You kissed my brother."

Yep. He saw.

"Jay. That wasn't at all what it looked like." Y/N says.

"Well to me, it looked like exactly what I saw." Jay retorts.

"I didn't want you to see it." Y/N whispers and rubs her temples.

"So you did kiss Will?!"

"No! Of course not! Will said he was having trouble telling if a girl he liked felt the same way, and I decided to tell him about us to use you as an example, but before I could get it out he kissed me!" Y/N exclaims, using her hands for special effect. "I'd never do that to you, and neither would Will! It was a mistake."

"But, you guys were so close to each other-." Jay cuts himself off.

"I was just trying to be a good friend, Jay." She says softly. "I love you. I'd never, ever, do that to you."

Jay looks at her, surprised.

That was the first time she's told him she loves him.

"It's ok. I get it." Jay says. "I guess I was just worried that I lost you to my own brother." He admits.

"No, never." Y/N hugs him and Jay just melts from her warm presence.

"And by the way. I love you too."
