Tonight on The Rookie, ABC continues its Cast From the Past Week with a nice reunion for star Nathan Fillion.
The Rookie episode titled “The Bet” will see both Seamus Dever and Jon Huertas reuniting with their old Castle co-star for the episode.
While a lot of Fillion fans might have been dreaming of a Firefly reunion for The Rookie, Castle was the more popular show with mainstream TV watchers.
Seamus Dever and Jon Huertas on Castle
Seamus Dever and Jon Huertas were two of the top detectives on Castle, working with Beckett (Stana Katic) and Castle (Fillion) to solve cases.
Seamus Dever starred on Castle as Kevin Ryan, while Jon Huertas portrayed Javier Esposito. The two men worked on the series for the entire eight-season run on the show, which ended when Stana Katic chose not to return.
Fans got to see a lot more of Huertas as he took on a role in the extremely popular NBC series This is Us as Jack’s best friend Miguel, who ended up marrying Rebecca over a decade after his friend’s death.
Huertas’ biggest role before Castle came in the HBO series Generation Kill as Sergeant Espera.
As for Sheamus Dever, he picked up a recurring role as the villain, Trigon, in the DC Universe series Titans.
Before Castle, Dever appeared in 173 episodes of the daytime soap opera General Hospital as Det. Kevin Ryan.
