You were currently being targeted by an unsub.

Someone had murdered your father, and there was reason to suspect that you were the next target.

To protect you, cops were posted up all around the outside of your house, and one of the FBI agents on the case was assigned to stay with you in your home until the unsub was in custody.

That agent was Dr. Spencer Reid.

He found himself seated on your couch, reaching into his bag for a book.

Of course, the girl he’s being forced to protect is really pretty, and he tends to have trouble talking to girls. Just his luck.

He tries to distract himself from that thought by reading.
