I am a Castle fan, but i have to say this episode was awful, very poor writing, nonsense dialogs, stupid situations, i mean, a writer saving the world in the jungle Rambo style? Come on, give us a break! A writer with a father that is in the CIA but have nothing to do with Castle disappearance, that promised him to never leave him alone but doesn't show up to help his son. Is just too much. Maybe the writers and producers of the show think we are stupid fans that just care about 'Caskett' and nothing else, or maybe they know there won't be a season 8 so they just wrap it up as they could. And i don't care for the 'Caskett' moments anymore, i feel that Stana Katic no longer brings anything to the show since season 6, enough with that. They are detectives of New York, why don't show interest cases to resolve? Like they do in 'Bones' for instance. Why should Castle have to continue then? Well, in episodes like Castle P.I. we saw the comedy acting power that Nathan Fillion has, make more shows like that one, it was hilarious! Even without Stana, Castle can investigate with Esposito and Ryan just well and send Beckett to the FBI or something, just get rid of her, and let the ones who want to be there, who want to do a good show. And writers please, don't destroy a beautiful show like Castle, get serious!
