How could you

What do you mean cheated on me

Lucy was on patrol with Aaron. Aaron knew something was wrong cause she was quiet.
A-"Lucy is everything ok, you seem down"
L-"Umm, yeah, just feel a bit sick"
A-"Ahh ok"
Lucy was quiet the rest of the time till lunch.

At lunch she went to get tacos and Tim was behind her. He went up behind her and grabbed her waist. Lucy's elbowed him in the face not knowing it was Tim.
T-"Luc what the hell"
L-"I'm so sorry, I didn't know it was you"
T-"Ok, well I'm going to go get cleaned up, can you get me something too"
L-"Umm yeah"
T-"Thank you, love you"
L-"Love you too, and I'm sorry again"
Lucy just stood there waiting. She got her and Tim's food then sat down. Tim came back and they both started to eat. Lucy was acting like the conversation with Angela and Nyla didn't happen and was talking to Tim. Angela and Nyla saw them and went to sit with them.
A-"Hey guys"
T-"Hey Ange, you've been busy today"
A-"No, Lucy have you been busy talking to someone"
L-"What"
A-"You know our conversation"
L-"No I haven't, I'm doing it tonight"
T-"Doing what tonight"
L-"It doesn't matter"
N-"Yes it does Lucy"
T-"What aren't you telling me Lucy"
L-"Nothing oh my gosh, it doesn't matter"
A-"Lucy, you should really tell him what it is"
L-"I will after work, otherwise he's gonna not be safe"
A-"Ok but if you don't do it tonight you know what I'll do"
T-"Don't threaten my girlfriend"
A-"Tim you'll be happy I'm threatening her"
T-"What does that mean"
L-"I'll tell you tonight"
Lucy got up and went to Aaron.
L-"Let's go"
A-"Yep"

(Time skip a couple of hours)

~at Lucy's apartment~
Lucy walked into her apartment and Tim was already there.
L-"How'd you get here before me"
T-"Because I did, now tell me what Angela and Nyla were talking about at lunch"
L-"Umm"
T-"Well are you going to talk or should I call Angela"
L-"Don't call her, it's just I have an appointment for an ultrasound"
T-"So she was threatening you over that"
L-"Yes, but it was a joke, I swear"
T-"Ok"
L-"Umm, I'm really tired so I'm gonna go to bed now"
T-"Ok, I'll come join after my shower"

~the next morning~
Tim woke up at 8am to Lucy's side empty, then he realised he slept in. Lucy was already at the station. He rushed to get ready.

Lucy walked into the locker room and got changed but before she could leave Angela came in.
A-"Hey Lucy, did you tell him"
L-"Bye Angela have a good day"
Angela grabbed Lucy's arm as she went to leave
A-"If you haven't told him I will, he is my best friend and doesn't deserve to be cheated on, then have to raise the child that night not be his"
L-"If you think that then why won't you date him"
A-"Because I see him as a brother, you tell me the truth on if you told him on not now"
L-"I told him now leave me alone"
Lucy walked out and Angela got changed then went to Greys office.

G-"Hey Lopez, how can u help you"
A-"I need to ride with Tim today, I'm on patrol today and Tim has nothing going on right now with metro"
G-"Yeah of course"
A-"Thank you"
Angela left Greys office and texted Tim

A-"Hey just so you know, today we're riding together"
T-"Ok, I'm here already I'm just getting changed"
A-"Ok I'll meet you at the shop"

Angela went to the shop and waited for Tim.

Tim got to the shop and they started to drive.

A-"So how'd you react to Lucy telling you she cheated on you"
T-"What do you mean cheated on me"
A-"That what I was threatening her about yesterday, if she didn't tell you that she cheated on you and that the baby might not be your then I was going to tell you"
T-"Well you just did, she said that you were just joking with each other and that it was that she had booked an ultrasound"
A-"Well that's not what it was about"
