Few years ago you were working at the BAU with Derek being you boyfriend, but one day he said that he's not ready for any commitment and you two broke up.

You decided to leave because of this pain every time you looked at him. You moved to another city and soon enough you found out that... You were pregnant.

You decided not to tell him about it, to raise this child alone. And now you were walking around the park near your apartment when you heard someone calling after you.
