So far Castle Season 5 hasn't delivered the usual nail-biting cliffhangers we've seen in previous seasons — but hold onto your seats, Castle fans. Show creator Andrew Marlowe has something huge planned for February sweeps, including the much-anticipated two-part episode. 

According to TV Guide, this season's "explosively personal" two-parter will explore a storyline that's been on the backburner since Season 4's double episode — Rick Castle's father!

As the story goes, Martha Rogers become pregnant after a one-night stand, and ended up raising Richard as a single mom. Not only has Rick never met his father, but he knows absolutely nothing about him. That is, until his former muse-turned-CIA operative-turned-Russian spy drops a major bombshell in Season 4, Episode 16: "Linchpin." Castle's dad may be connected to the CIA!

TV Guide reports that the introduction of the missing patriarch will "profoundly impact both his son's and granddaughter Alexis' lives." Consider our curiosity piqued!

We've been speculating for ages about Castle's puzzling pops, particularly what he looks like. Nathan Fillion has tossed around a few A-list names, including Harrison Ford and Chris Walken, and we composed our own list of potential padres. Although there's no concrete casting news at the moment, we can rest assured that the apple didn't fall far from the tree.

"I'm pretty sure he's ruggedly handsome," Marlowe joked.
