Emily's murder weapon a private joke?
Has anyone else ever noticed the frequency and detail with which Emily's knife is shown, both in her overnight bag, and being wielded by her? The handyman who sharpens it for her specifically states that he's never seen one like it, and Emily responds that it's a knife used for surgery. When he asks her what she uses it for, she doesn't answer.
I find it hard to believe that the specific choice of this type of knife wasn't deliberate, on either Castle or screen writer White's part. Taken together with the references to Denmark, it has to be a perverse joke, referring to Emily's (presumed) sex change surgery to make her into Warren.Thus, her use of it to murder the people responsible for her miserable condition becomes a sort of poetic justice. ( Notice the crazy, infuriated look she gets, right before stabbing the justice of the peace, when he lecherously announces " Now I get to kiss the young lady").
And when he crossed the bridge, the phantoms came to meet him
