Steven Culp, who I see as Tommy 2000 AKA Tommy McFarland
For Tommy to really be a mature creation, he needs complex emotions. With Dave, he feels jealousy. As Peri puts it, he's supposed to be like a loyal dog. But he doesn't like it when she plays with other dogs. He never gets violent or anything. But Tommy is clearly wounded and he is short with Peri when she tries to talk to him about it.
