Gould was shocked when he read the script for the show's fifth season finale, in which his character, Shane Botwin, clocks and kills Pilar, his mother's nemesis, with a croquet mallet. Because of that murder, Season 6 takes place on the run, and an ever-darkening Shane isn't exactly remorseful. Nancy (Mary-Louise Parker) has tried to reboot her wayward son's moral education, but, well, Shane has always been a little off. Gould, now 16, tells us how Shane has changed over six seasons, why he loves playing Shane as a mini-Dexter and whether he thinks he's capable of killing again.
TVGuide.com: What was your reaction when you found out that Shane was going to kill somebody?
Alexander Gould: I was just as shocked as everyone else. I just got the script. Most seasons we don't get the end of the script, so nobody knows what's going to happen so we can't tell anybody. So when I got the last couple pages of the script, I was surprised to even be in the scene. I thought it was cool, but it was also tough because I'm not a violent person. I was really nervous I was going to hurt [Kate del Castillo, who played Pilar]. It was a little awkward.
TVGuide.com: Have you ever watched Dexter?
Gould: I haven't, but I have talked a little bit about Shane being like Dexter.
TVGuide.com: Shane used to be very morally judgmental of his mother. What was the turning point for him?
Gould: I think we have progressively seen Shane get darker and more violent. In Season 5, he kind of broke when he got shot. There's a point early in the season when he was saying that the people in the drug cartel are monsters and that they need to be careful. Then he started almost siding with them and then he got shot. And that changes him. He figures if he can't beat 'em, he'll join 'em.
TVGuide.com: Do you think Shane is capable of killing again? Or was Pilar's death an isolated incident?
Gould: I think Shane has the potential to kill again. He's definitely not opposed to the idea. Whether he will or not is another question. But it's definitely a possibility.
TVGuide.com: Think back to when you were 10 and you first signed on to this gig. What was Shane like then?
Gould: He was as normal as could be, given the circumstances. When he learned about his mother's operation, he became sort of like the family's moral compass. I remember early on I had to say the F-word and I was really hesitant about it. Over time, Shane just got more confident and odd. I felt like Shane really was just [slowly] going crazy. He put that craziness away and it manifested itself in a funny way. He always seemed a little out of it.
TVGuide.com: Did you always understand what was going on on the show?
Gould: No. My parents wouldn't let me watch it. I knew the basics — drugs and stuff — but that was about it. Now I go back and watch it and think, "Oh, that's what that was. It makes a lot more sense now."
TVGuide.com: What's next for the Botwins/Newmans?
Gould: The family will be on the run for the rest of the season with the FBI and Esteban hot on their trail. They need a different escape route, so they decide to move in a different direction, and they get close to getting caught a few times. It's a really fun, classic Weeds season.
