November sweeps is fast approaching and Castle will finally bring Rick's mother, Martha, and Kate's dad, Jim, together. The two lovebirds plan a 'meet the folks' dinner for their respective parents, but unfortunately, it's on the same night that Castle and Beckett get stranded without their phones while protecting a witness from the mob. Creator Andrew Marlowe spoils that it's like oil and water.
