Sergei doesn’t like this, doesn’t like that the boy is almost at it [his goldfish], already reaching for the jar. In this instant Sergei understands the boy didn’t come for television, what he came for, specifically, is to snatch Sergei’s fish, to steal it away. Before the mind of Sergei Goralick really understands what it is his body has done, he seems to have taken the burner off the stove and hit the boy in the head. The boy falls. The camera falls with him. The camera breaks open on the floor, along with the boy’s skull. There’s a lot of blood coming out of the head, and Sergei really doesn’t know what to do.
That is, he knows exactly what to do, but it really would complicate things. Because if he takes this kid to the hospital, people are going to ask what happened, and it would take things in a direction Sergei doesn’t want to go.
“No reason to take him to the hospital anyway,” says the goldfish, in Russian. “That one’s already dead.”
“He can’t be dead,” Sergei says, with a moan. “I barely touched him. It’s only a burner. Only a little thing.” Sergei holds it up to the fish, taps it against his own skull to prove it. “It’s not even that hard.”
“Maybe not,” says the fish. “But, apparently, it’s harder than that kid’s head.”
“He wanted to take you from me,” Sergei says, almost crying.
“Nonsense,” the fish says. “He was only here to make a little something for TV.”
“But he said . . . ”
“He said,” says the fish, interrupting, “exactly what he was doing. But you didn’t get it. Honestly, your Hebrew, it’s terrible.”
“Yours is better?” Sergei says. “Yours is so great?”
“Yes. Mine’s supergreat,” the goldfish says, sounding impatient.
‘‘I’m a magic fish. I’m fluent in everything.” All the while the puddle of blood from the earring kid’s head is getting bigger and bigger and Sergei is on his toes, up against the kitchen wall, desperate not to step in it, not to get blood on his feet.
"You do have one wish left," the fish reminds Sergei. He says it easy like that, as if Sergei doesn't know-as if either of them ever loses count.
"No," Sergei says. He's shaking his head from side to side. "I can't," he says. "I've been saving it. Saving it for something."
"For what?" the fish says.
But Sergei won't answer.

What does the dialogue(Conversation between two or more people) between Sergei and the Goldfish reveal about their relationship?
