Castle mentions that Simon's story sounds like a mix between 12 Monkeys and The Terminator. Beckett requests a psychiatric evaluation of Simon and when the psychiatrist arrives he introduces himself as Dr Silberman. The same name as the psychiatrist played by Earl Boen in the first three Terminator movies. See more »


In all but one shot, Paul Deschile's letter shows his school as P.S. 311. However, the copy Beckett spills coffee on at 40:16 is P.S. 370. After she blots the letter, it is back to P.S. 311. See more »

Richard Castle: [entering the loft, he sees Pi's stuff is gone] You're really doing this.
Alexis Castle: I am. I know what you're thinking. You're thinking I'm making a huge mistake.
Richard Castle: What if you are? This isn't something you can just go back and undo. Why don't you wait a year, okay? Move into the dorms; I'm sure Pi can take care of himself, and if after a year you still want to move in together, I... I won't say a word.

An excellent episode
18 November 2015 | by See all my reviews

I was not the greatest fan of season 5, so I entered season 6 with low expectations. But the first episodes were quite good, in my opinion, Time Will Tell being one of the highlights.

It all starts as with every other episode, a killing. One guy was running away from the scene, and Castle and Beckett's investigation centers on finding the suspect. They do, but soon discover they are in for a weird one: he claims he is from the future.

The best episodes of Castle had a great mixture of tongue-in-cheek humor, good chemistry between the actors and a nice mystery. This episode fills all three boxes. There's some nice banter, sci-fi references (Doctor Who, Terminator...), a great guest in Joshua Gomez as the time traveler, and a mystery that offers more than a couple of nice surprises. It all centers around the "does he come from the future or not" a little bit too much, but that's exactly the point of the episode, and why it is so much fun. Fillion is at the top of his game as Castle in this kind of episodes and everyone else follows him through. Great from start to finish.
