So a season ago Kate is going crazy about the missing child. But in this episode, you find a man, you don't find the child with him and you don't believe him. You keep accusing him, instead of believing there's a missing kid first and guilty father second.
I know she has a job to do but to me, you put the child at risk but ignoring the father. They should've stayed there at the hotel with him. Question him there or whatever. "talking to cops will kill him" ok then let's bring him to the police station? I don't know, I thought Kate was acting sloppy. Especially since we constantly hear how she's the best detective ever.
Interesting episode, I liked how it linked to this kidnapping.
I liked Ashley's reaction to the rat being lost, it was sweet. I liked Martha's scream at the end with Castle's "found him"
