You haven't seen him for at least a whole year. After almost a decade together and four years of marriage, Spencer Walter Reid cheated on you with Maeve Donovan, a geneticist who helped him treating his migraine.
The thing that hurt you the most was the fact that he emotionally cheated on you. They spent six months talking and falling in love with each other over the phone before she was brutally killed by her stalker.
Spencer was destroyed by it, and you were too. Not only he cheated on you, he suffered from the death of his beloved and you stuck by his side anyway. Until you couldn't do it anymore, and you sent him your divorce papers.
It was three years ago, but you moved to New York last year. You wanted to move on, to build a new life. Hell, you were one of the most important lawyers back in DC, your career was brilliant.
So you did it. You moved on. You lived in the Big Apple, you found yourself some friends, and you won every case in court.
You moved on until Emily Prentiss called you. She said that Spencer was arrested for a crime he didn't commit: he was charged of the murder of Nadie Ramos, a mexican lady. The BAU was sure of the fact that he was framed by someone, probably Mr. Scratch.
"He would have never called you because he doesn't want to bother you, but he needs you. You are the best lawyer we know, the FBI abandoned him. You are the only one who can pull him out of there. He's innocent."
And here you are, after two days of Emily's call, sitting in a shitty meeting room of a federal prison. After a few minutes a guard brings Spencer in, closing the door behind him. And there he is: his hair is longer, he has a slight stubble on his face, eyebags really evident. He's barely shocked to see you.
He's quiet for a few seconds before he says:
"You shouldn't be here."
