In the previous episode of "Castle," Kate Beckett (Stana Katic) got her NYPD badge back. Also, Rick Castle (Nathan Fillion) was allowed to come back to the 12th Precinct as the consultant. The two are officially back, together to solve a new murder mystery. It is going to be interesting to watch how the two manage to keep-off each other at the workplace, since they are engaged now.

This will be the first time, Beckett and Castle will be really together after their engagement. Beckett had gone to Washington D.C. right after accepting Castle's marriage proposal. She got fired from her job at the Attorney General's office, and is back to where she originally belongs, with her usual NYPD team and Castle. There will be romance for sure, but we can expect fireworks, too.

The fifth episode of "Castle" Season 6 is called "Time Will Tell." The murder suspect in this episode is someone who claims to be from the future. Simon Doyle will guest star as the murder suspect, Joshua Gomez.

In "Time Will Tell," which is written by Terri Edda Miller and Andrew W. Marlowe, and directed by Rob Bowman, Castle and Beckett are expected to solve a "grisly murder." As per the Promo, when Beckett handcuffs the suspect, he tells them that they do not know what they are doing. He asks Beckett to let him go or million people will die ... "because I'm from the future." The moment he mentions that he belongs to the future, the murder case becomes the favourite case of Castle.

According to the official synopsis of "Time Will Tell": "A grisly murder investigation leads Castle and Beckett to a suspect who claims he's traveled back in time to stop terrible events from unfolding, events that will change the course of human history. Is he simply a deluded killer, or is it possible that he's telling the truth."
