We love the more lighthearted episodes of Castle, but we live for the stories that motivate our favorite characters. 

And on Monday, Feb. 4 Castle returns with a brand-new episode centered on Johanna Beckett’s murder and sleazy Senator William H. Bracken who was responsible.

The synopsis reads:

“While investigating the murder of a young woman, Castle and Beckett find evidence that links her death with Senator William H. Bracken (guest star Jack Coleman returns), the man responsible for Beckett's mother's murder. Determined to finally bring Bracken to justice, Beckett soon realizes that things are far more complicated than they seem.”

And not only is he showing his face again, but according to the promo, Beckett will be forced to protect the man responsible for her mother’s murder!

Do you think Beckett will be able to put aside her personal feelings and do her job or will she try to take out the senator? Tell us below!
