The fifth and final season of 'The Wire,' which is arguably the best television show on the air, returns to HBO on Sunday night.

Curious fans of the gritty drama have waited over a year to find out the resolution between Marlo and Omar and if McNulty falls off the sobriety wagon.

One of the most endearing characters from Season 4 is Bubbles, the homeless heroin addict who is portrayed by Andre Royo.

Bubbles took fans on a emotional roller coaster as we saw his relationship with young Sherrod before he ended up accidentally killing him and ending up in the rehab center.

What's planned for Bubbles in Sesason 5? Royo spills the dirt about his character on the show and who would win in the ultimate 'Wire' street fight.

Season 4 was big for Bubbles. We saw a lot of progress since Season 1. Will Bubbles ever become clean?

All the way? I don't know. I know I portray Bubbles but Bubbles was a real life character that was Ed Burns informant and we talked about his real life when he passed away. Was he ever fully clean? I don't know. Bubbles has to deal with living life without a specific purpose for the first time. Not trying to get high or trying to get money or ways to get high. It puts him in a different mind frame when he leaves the rehab center. It's a very depressing and spiritual journey where Bubbles has to find his purpose in life when he's not worried about trying to get high. Will that hold? Let's hope so.

What season of 'The Wire' was the best storyline for your character Bubbles?

I think the first season. When I got the part, they told me maybe seven episodes. They guaranteed seven but they weren't sure where the character was going from there. I'm playing this junkie informant and that's what they were going to use me for. In the first season, I started off that way but all of a sudden, my storyline spun off and removed itself from the cops and robbers. There was one statement that my friend Sonja [Sohn] who plays Kima that was really my motto in trying to stay clean. When I asked her for money because I wanted to stay clean in the first season, she said "What am I going to do with a clean snitch?" That resonated how this character in dealing with the police that is there to protect and serve, they were like we don't mind you getting high. We don't mind paying you to get high as long as we get the information that we need.

With such an amazing show, why do you think the ratings have been so low and why the lack of respect from the voting academy?

I have always had a problem with the ratings scale because they would judge Sunday at 9:00pm only. And our audience wasn't watching it Sunday. Anyone who had HBO knew they were going to replay it on Wednesday and replay it on Monday at 11pm. It came on at the same time during the basketball game. Our first season aired during the playoffs, so I would call my boys and they would be like I'm watching the Lakers vs. Kings, I will catch it on Wednesday. We couldn't get a true estimate of how many fans we had because people weren't watching it at that specific time. We are the highest ranking show on HBO On Demand. They were going to cancel us during the second season but when the first season came out on DVD, we sold 300,000 copies quickly. HBO found out we had an audience. They realized they couldn't judge that audience on the old school ratings techniques. As far as the Emmys are concerned, we just gave up as to why. There are a plethora of reasons why. We shoot in Baltimore and they say if you don't shoot in LA or NY, you are outside of the entertainment field. You have a storyline that is very complex and if the Emmy board, SAG, whoever might be, watch one or two episodes, they won't get it. You can't watch one or two episodes and get 'The Wire.'

Which of the following characters would win in a street fight? Marlo, Omar, String Bell, or Avon?

In a street fight, I would have to go with Marlo. He won't stop and there is nothing he won't do. Omar might not cheat. He has a code. Omar will take a break on Sunday. He might want to play basketball. Stringer Bell doesn't want to get his suit dirty. Avon will take a break on a Sunday too. Remember he said he couldn't shoot at Omar on a Sunday because it was against the code. Marlo doesn't have any of that. Whatever it takes.

Are we going to see conclusion between Marlo and Omar this season?

You are going to see something. That has to come to a climax. That story will be told and that question will be answered.

What is your favorite version of the theme song out of the last five seasons?

Personally, my favorite was the second season. I like that little beat it had to it. Second season was my favorite.

What's next for you in your career?

Right now, I am just enjoying being a dad. I'm just going to stay home and be a good daddy, take care of my wife. When you are shooting in Baltimore six months out of the year, you kind of miss home. I have a movie that's in Sundance with Josh Hartnett called August and I was doing a couple episodes of the 'Sarah Connor Chronicles' but we had to stop because of the strike.
