At the end of last season Beckett and the team got a shock when they found the third cop involved in her mothers death was their one and only Captain Roy Montgomery. Trying to protect her, Captain Montgomery gave his own life thinking that he would end it all. Unfortunately he gave the people behind the conspiracy to much credit as at the Captains funeral Kate Beckett was shot down by a sniper while giving her respects. Castle tackling her to the ground in a challenge to protect her, realizes he was too late and in a last desperate hope to tell her everything he whispers the four little words every viewer has been waiting for for the last 3 seasons "I love you Kate."
Now the waiting was over for all the fans Monday night as the opening scene shows trolley wheels sliding around on a floor full of blood as they rush Kate into the hospital emergency room with her best friend and medical examiner Lanie on top of here doing CPR, and Castle not far behind. Rushing her into the ER Kate's doctor boyfriend Josh who is on duty at the time recognizes her.
Leaving the ER room an angry Josh walks towards Kate's friends and father yelling about how a cop gets shot at another cops funeral. When Castle tries to step in and let him know he tried to help her Josh shoves Castle into the hospital wall and proceeds to blame him not only for Kate getting shot but also for the Captains death. Now this confrontation has been building up as everyone, including co-workers know that Castle and Beckett have a very strong relationship, so we can assume that Josh has realized this as well and feels threatened. However Castle starts to agree with Josh, if only he never tried to convince Kate to reopen her mothers case everyone would still be alive.
When Castle proceeds to talk to Beckett in the recovery room the next day, he assumes she heard everything he told her, including his confession, but is shocked not only to hear that she "blacked out" but also that she wants her space. Knowing Kate, viewers most likely saw right through this and assumed right off that bat that she was lying from Castle and was trying to run away from her feelings.
Flash forward to a couple months later and Beckett returns to the precinct to a new captain, "Iron" Gates, no Castle and her shooting case being dropped. Determined more than ever she returns to the case that is not permitted by her Captain, and reconciles with Castle, promising him one day, once everything is behind them, they can finally be together. While at the same time Castle gets a call from an old friend of Captain Montgomery's who has all the files from Roy's collection about the case of Kate's mothers murder and convinces Castle to keep Kate away from the investigation in order to keep her safe.
In the end Kate promises to take a step back but at the same time confides in a psychiatrist about hearing Castle's love confession, and who she is without her mothers case.
I doubt anyone who actually reads my blog watches Castle but if you do, please feel free to comment. If not please give me tips on how to write my reviews better.
