Your dad David Rossi had you when he and your mother were 15 so you were always more like a little sister than a daughter to him

You had met one of his work friends Erin Strauss when you were around 20 and she was 30 but nothing ever happened even though you always thought she was attractive

You had just got out of the FBI academy for wanting to join the BAU like your father and you and him were talking about the BAU and he mentioned that his friend Erin is the Section Cheif of the unit
