We see Castle and Becket enter an apartment building where uniforms and techs are taking crime scene photos in a child’s room. Captain Montgomery breaks the situation down—two-year-old Angela Candela was abducted from the apartment that morning. The Feds tell Beckett that William Sorenson, the special agent in charge of the investigation, requested that she take part in the task force.Next we see Sorenson enter the room, and Beckett immediately reacts. Castle can tell there’s history between them. Sorenson promises Beckett that this case will “end better.”At the precinct, Beckett admits to Castle that she and Sorenson dated for six months. We knew it! They met during a kidnapping case, but we can tell there’s more to the story.Ryan fills them in on the parents. Married ten years, Theresa is a fund manager and Alfred is a struggling artist. Angela is their only child, and was adopted. Alfred says he and Angela had the same morning routine every day. Beckett feels this must mean the abductor knew their routine.
