Who are you? What are you? Why are you?

Ryan asked these questions of Wilfred during a fit of hysteria in "Identity," and I for one, cannot wait to find out the answers.

Throughout the season finale, Ryan slipped deeper and deeper down the proverbial slope, to a point where he was back to using dirt to win cases, switching urine to save clients, and basically doing whatever it takes to get the job done.

What did it cost him? Well, he forced his pregnant sister to leave her husband and move to India. He pushed Jenna to marry Drew, because she believes that she has a baby on the way. And he caused his pal Wilfred to jump in front of a moving car, which severely injured him, and might have rid him of his memories.

But after Wilfred's fit of amnesia, be it real or artificial, Ryan remembered that the dog was recently writing a will that could help Ryan know what to do if anything happens to [him].

I was expecting the will to be a joke by Wilfred, saying something to the effect of I can't believe you thought I lost my memory, but instead, when Ryan got to the door of his beloved basement, he found a closet! The basement that he has been hanging out with Wilfred in for the entire season has been imaginary? Is that what we are being ed to believe?

It was pure cojones by the writing staff to come up with that development. I mean, who ends a season of a comedy like that? Wilfred does, and it was brilliant. There can't be any sort of finality to what exactly this hallucination is until the series ends, but the continuing feeling that we might find out keeps the audience on its feet.

That makes Wilfred different from any other sitcom on television, and yes this is a straight-up comedy. It's not like Louie or any of the Showtime dramedies, where it is up for debate on how to categorize them. Wilfred is hilarious week in and week out, it just so happens that along with being funny, it is also very strange, and really makes you think. That was no different in "Identity."

When you have Wilfred drinking bong water like it is coffee, being distracted by bubbles three times in four minutes, and really wanting to go to India after hearing about the dirt, feces, and decaying animals, you have a recipe for hilarity.  

Does there need to be growth from some of the characters as season two moves forward? Absolutely, but we've seen some of that already. Wilfred, be he real, a part of Ryan's mind, or something else entirely, has had moments of sincerity during the first season, and I see that continuing next year. Will Ryan continue to improve? Probably, but it won't be a quick process or there wouldn't be a show left to put on the air.

Wilfred is a series about Ryan's problems, and the fact that those problems lead to him seeing this dog as a man. That leads to hilarious hijinks week after week, and it has certainly been a funny first 13 episodes.Bring on the next 13.
