On Castle, we’re used to Rick making a few literary puns, but he and Kate are going into full-on geek mode in next week’s episode.

As we know, in Castle Season 5, Episode 6: “The Final Frontier,” our favorite duo takes a trip to a sci-fi convention, which has Comic-Con meta storylines written all over it.

Not only will we get to hear Castle talk about double-bladed lightsabers, but we’ll also hear Beckett say her fair share about sci-fi weaponry!

In a new sneak peek clip, Castle and Beckett talk geeky to guest star Armin Shimerman (of Star Trek: Deep Space Nine fame) — all in the name of the case, of course!

Check out the clip below, and then share your thoughts in the comments.

Castle Season 5, Episode 6: "The Final Frontier" airs on Monday, Nov. 5, 2012 at 10 p.m. ET on ABC.
