Hi i'm a Lebanese Castle fan (and I just re-wrote this post for the third time because the page crashes when I try to reply using my iPad, argh!). I live/work in Saudi Arabia in Jeddah and now am in holiday in London. 

I got hooked to Castle quite late in the game. It was on a lazy thursday weekend afternoon about 3/4 weeks ago. I caught a season 2 episode on Showtime .. the one with Alyssa Milano, can't recall the ep name atm.

After watching the brilliant acting, the clever dialogue, great writing and the chemistry between Castle and Beckett I was hooked and went back and started watching the show from 1x01 till the latest episode at that time 4x20 I think the "Limey". So yeah I got so hooked and watched 80 episodes over a 1 week period.  What a rollercoaster of emotions especially to the end at the low point in C&B's relationship in 47 seconds. Watching the episodes one after the other I could really see how the characters were changing before my eyes and how their relationship was heading to eventually have them together as per 4x23 what an amazing episode I can't stop re-watching it. It reached really a point like AM said that there was no more obstacle for them to not be together.

Sorry for my long first post just wanted to also voice and say Castle definitely has fans in the arab world ! Epic love stories tend to have universal appeal
