We watch Castle for the "who done it", the witty and flirty and sometimes hot interplay between Beckett and Castle, and this new plot line is awful. It's not even a little plausible after everything Beckett and Castle have been through. If Beckett and Castle are not together again really soon, I will tune out this season. Already tuned out halfway through today.
I am a true fan of Castle and would be truly disappointed if it were cancelled it is truly entertaining
