Emily x reader
Request: Emily Prentiss x female reader + Derek Morgan: Derek cares about the reader like she’s his younger sister, so he’s extremely protective of her especially when she dates. When the team is called in for an emergency, the reader shows up in a nice dress, Morgan thinks she’s seeing someone and didn’t tell him. He becomes suspicious, so he kind of follows her and profiles her. On his “˜search”, he figures out that she’s seeing Prentiss. He eventually gives Emily the talk, but supports them.
Derek had always seen you as a sister which meant he was pretty overprotective of you and no one you dated was ever good enough for you.
When you started seeing Emily you decided it was best to keep it from him and the rest of the team until the time was right.
You were getting ready to meet up with Emily for your date but were interrupted by a call requesting everyone report for an emergency case.
Stepping out of the elevator onto the BAU floor of Quantico everyone stopped and stared at you in your heels and nice dress which you didn’t have to change out of.
You just as easily got the attention of your entire team when you walked into the already packed briefing room.
“Woah Y/N, somebody’s all dressed up,” Penelope teased.
“Yeah Y/N, did you have a date or something,” Derek said raising an eyebrow.
You glanced over to Emily nervously who was standing at the head of the table.
“What, a girl can’t just have a night out on the town on her own?” you said collecting yourself as you took a seat.
The rest of the team shrugged it off and got back to the more important matters at hand, your case, but Derek still had his suspicions and was determined to figure out what was going on.
For the next few weeks Derek kept his tabs on you, profiling you, checking out your social media to see if you were talking to anyone in particular and even dropped by your apartment a few time unannounced just to ‘hang out’.
One day at work Derek overheard you tell JJ that you had plans to go see a movie that night.
He arrived at the movie theater and parked his car across the street.
He kept watch on the entrance and fifteen minutes later you showed up.
“Alright Y/N, who are you meeting up with,” he said to himself.
A few minutes passed and Emily came up behind you, placing her arms around your waist and kissing your cheek.
Derek watched as you turned around in her arms and properly kissed her hello.
“Emily?” Derek muttered in shock.
He was disappointed that you didn’t tell him about you and Emily but he figured you had a good reason for not doing so.
He kept his discovery to himself for as long as he could but after seeing you and Emily sitting a little too close to each other on the plane ride home from a case, he just couldn’t stay quiet anymore.
“Hey Emily can I talk to you for a second?” He asked as everyone was saying their goodnights.
The pair stepped into her office and Derek shut the door behind them.
“Is everything okay Derek?” Emily asked.
“Yeah, yeah it’s fine, it’s just about Y/N.”
“What about Y/N?” Emily said caught off guard.
“I know you two are seeing each other,” he explained.
“No, no you don’t have to explain yourselves to me, I just wanted you to know that I fully support you guys,” he said cutting her off.
“That’s great to hear,” Emily said relieved.
“Y/N is like family to me, all I want is for her to be happy and to be taken care of by someone who loves her and respects her.”
“Derek, I love Y/N very much and I will always respect her.”
“I know you will,” Derek smiled.
Later that night Derek was getting into bed when his phone vibrated notifying him of a text.
He looked at the screen to see the message was from you and read ‘Thank you Derek’ with a heart attached.
