Because you're good at it. You really capture his essence.
Stanley: Martin, how are you feeling about your solitary confinement?
Martin: Well, first of all, it's great to be back. Um, I have to tell you, Stanley, I was in a pretty bad place. I thought my son was dead. It got a little dark there for a minute. But I have come to learn my boy is just fine. I was even able to help him with something explosive at work today.
Stanley: Well, that's positive.
Martin: But I worry about him. He's not OK. And I'm not sure I have the emotional tools to help. I was thinking we can do some roleplaying to help me with my self-destructive behaviors.
Stanley: Alright, Martin. Let's see --
Martin: And Hector can play Malcolm.
Hector: I don't want to. I'm always Malcolm.
Martin: Because you're good at it. You really capture his essence.
