Are you ready to see "Castle" tackle time travel? Well, get ready, because that's what's coming up in episode 605, "Time Will Tell," for which ABC released an official description and promotional photos on Monday, Oct. 7.
In this upcoming "Castle" episode, a grisly murder investigation leads Castle (Nathan Fillion) and Beckett (Stana Katic) to a suspect, Simon Doyle (guest star "Chuck's" Joshua Gomez), who claims he has traveled back in time to stop terrible events from happening, events that will change the course of human history. (And so here's a timeline for when Beckett returns to the NYPD.) Is Simon a deluded killer or could he actually be telling the truth? It sounds like this should be another fun episode.
The "Time Will Tell" photos in the slideshow offer a look at guest star Gomez facing questions from Beckett and Castle (and that should be very entertaining), as well as the team working the case.
"Castle" season 6 airs Mondays at 10 p.m. on ABC. "Time Will Tell" airs Oct. 21. What do you think of these episode 5 photos?
