Brandi in Boise, Idaho: Any fun scoop on the relationship between Castle and his daughter, Alexis, this season?"It's still strong," Molly Quinn tells us of the bond between Castle and his (not-so) little girl. "They're really depending on each other." Molly also says she's getting a more grown-up storyline: "Alexis is falling in love. We're going to see that take over a little bit. I wouldn't say her grades are going to slip, but she's going to have to learn how to balance having a love life and having to take care of her dad."
