I am exhausted after watching the Season Finale. Wow. Just......wow!! Whereas the Finale for Season 3 was kind of a letdown, this one was not. It left me reeling and out of breath and then the cliffhanger just absolutely floored me. I did not see that coming because I just assumed the Rita and Harrison got out of the City in time and that they were safe. But after Dexter played her voicemail on his Cell Phone, I knew that something was wrong. With Rita dead in a pool of her own blood in the bathtub, it's unclear to me if she killed herself or if the Arthur got in one last kill before Dexter caught up with him on the side of the road. I can't see how he would have had time to do so since he was on the run. But Rita seemed content and truly happy at the end, so killing herself makes no sense. I am remembering that when Arthur did a search online for 'Dexter Morgan', he got a hit on his home address, which he wrote down. So, I am confident that he did in fact killed Rita, just like all the other bathtub murders. I'm refraining from doing any online search myself to remain spoiler free till I can get a hold of Season 5 on DVD.

The other bombshell was of course Deb finally completing the puzzle about her father Harry and Laura Moser and discovering that Brian Moser aka The Ice Truck Killer and Dexter were brothers. But that's all she knows. For now. Her confessional when she tells Dexter what she knows was very powerful and heartbreaking at the same time and had me holding my breath the entire time. No wonder I'm totally exhausted.

Just like Jimmy Smits role last season, John Lithgow turned in an amazing, powerful performance and just absolutely shattered my perception of him. It's going to be very hard to look at him the same way. He just annihilated his goody two-shoes persona. I really hope he got an Emmy Nomiation and win for his role here. He absolutely deserves it.
