Fan Casting A long, long Time Ago in Ant-Man and the Wasp: Little Big Heroes

The scene shows a boy playing while his parents talk. - Feel all my wrath, worldly creature! [He rips the ragdoll's head off]. - Take it easy, son. - Okay, dad, I know! [He goes to the window]. - He's just a kid. - For now it's a kid, you mean. - I know what you're thinking, but he doesn't need to worry about that right now. Let him be a child. - Oh, you won. Before the scene ends, the boy looks at the view from the window of his house, contemplating the horizon, while saying to himself smiling: '- Let everyone get ready. Everyone will know my name!'; The screen goes black, before one last sound is heard: a thunder. The end credits roll.
