Maybe it was all the Christmas decorations scattered throughout "Do You See What I See?," but I feel like Dexter just gave us the gift of one of the best episodes of this season.

It wasn't without its flaws, like Quinn searching for Nadia only to find she's run off to Vegas, or gratuitous Masuka as an elf, but tonight's installment of our favorite serial killer drama had me looking toward Dexter's future as much as he did.

The opening scene tonight was Dexter, aged 15 years, living happily ever after with Hannah (who hadn't aged a bit) and Harrison, still killing when he needs to kill. It made me think "Could he do this forever?"

Sadly, the answer to that question is no. All things--good and bad--must come to an end.

Like Dexter's relationship with Hannah, which was both good and bad.

I found myself moved and saddened by his interactions with Hannah tonight. He's finally found someone who accepts all of him, but it can't last. It may be odd to say this, but it was almost touching when she basically congratulated him on finally having the opportunity to kill Hector Estrada. It was just a casual acknowledgement that this is what he does and she's okay with it. She accepts it.

But it was clear that her conversation with Deb wouldn't lead to anywhere good for she and Dexter. Deb and Hannah, the two women in Dexter's life, have been circling each other like animals before a fight all season long. Hannah decided to strike before Deb got the chance but perhaps miscalculated, thinking too highly of her skills.

All Dexter wanted for Christmas was for the truth to reveal that Hannah hadn't done what he knew she was capable of doing. Maybe he's been a bad boy this year.

Even if it turns out that it wasn't Hannah who poisoned Deb, and I'll admit to hoping for a twist like that, Dexter will never be able to trust Hannah. Not completely. He knows what she's capable of, has always known, and her method of killing, unlike his, is a little harder to see coming. Dexter wouldn't take that chance with Harrison or himself.

I'm not supposed to root for serial killers to be happy, but I did. However, the future Dexter and Hannah wanted was one based on the two of them being normal, everyday people, and the two of them are anything but.

It was almost heartbreaking to watch him turn Hannah in for the murder of Sal Price. The thought that she knows his dark secrets and is alive to possibly tell them is interesting as we look toward the finale and next season.

Dexter believes that the only moment in which he can live is the present one. That the future is too uncertain for thoughts about it to be entertained.

Well, he better start entertaining some thoughts because La Guerta is on to him in a big way, even after the evidence discovery in the abandoned boathouse.

I knew that she wouldn't give up her quest to prove that Dexter is the Bay Harbor Butcher after finding the evidence in the shed. It was too easy. She's nearly as rabid about discovering the truth as Doakes was before he died, which does make for a nice parallel.

Having Hector Estrada released from prison was a genius move on her part. She knew that if Dexter were the Bay Harbor Butcher, he wouldn't hesitate to take out Estrada. She's seen the kill room wrapped in plastic, which few have seen before, and knows that Dexter would have wanted him dead. He escaped, but what happens now?

Dexter's future is looking awfully grim at this point, but I'm excited to see if our protagonist will prevail.

What did you think of "Do You See What I See?" Were you sad to see the end of Hannah and Dexter?
