Listen up, Castle fans! By now you’ve heard that Rick Castle will meet his MIA father for the first time during the February sweeps two-part episode beginning February 18. But what you probably didn’t know is that the two will pair up for Castle’s most personal mission ever!

According to TVGuide, the two Castle men will join forces in the February 25 episode when the youngest Castle, Alexis, is kidnapped. Though Alexis puts up a good fight, her efforts are thwarted and she “kind of falls apart.” And she’s not the only one who starts to lose it.

Producer/creator Andrew Marlowe says that we’ll also see Castle shed some tears as he becomes “the powerless dad who fears for his child's life.Poor Rick.

Will Grandpa Castle save the day? Apparently Papa Castle, played by guest star James Brolin, will have “a strong hand in how ­everything gets resolved.” Maybe he’ll use some of those CIA skills he’s hinted to have.

As for any more details on the episodes, Andrew’s been on the hush-hush but he did say "there will be a moment between father and son when Castle comes to a realization and the two men confront the realities of their relationship."

Hmm … bring it on.
