The Heart Wants What the Heart Wants
Beckett has started dating Detective Tom Demming, much to Castle's chagrin. But when Madison Queller (an old high school friend of Beckett's) pops up in connection to a murder investigation, Castle is immediately intrigued and asks her out. Castle and Madison share a tasty dinner at celeb chef Rocco DiSpirito's restaurant. When new evidence comes to light that may implicate Madison in the murder, Beckett has a convenient reason to break up the dinner date.
Back at the station, Madison immediately rips into Beckett, accusing her of breaking up her date for personal reasons. "You're hot for Castle! You want to make little Castle babies!" The funny thing is, Beckett doesn't deny it! She's too mortified by the fact that Castle can witnessed their exchange from outside the interrogation room! Gotta love those two-way mirrors!
