The personal life of Rick Castle collides with the possible end of our country as we know it tomorrow night.

Indeed, this ABC hit will wrap up its annual two-part episode with "Linchpin," an installment that once again features Jennifer Beals as CIA agent Sophia Turner... and she's none too happy with Castle.

In the first of two clips from the outing, watch as Sophia reams Castle out about the supposed mistakes he made in tracking an event that has put us on "the verge of the next 9/11," while concluding her speech with a reference to her past with this author. Awkward!

Then, watch as Castle must fend off inquiries about his history from both Beckett and Alexis. Someone sure sounds jealous...
