This scene represents the exposition of the story in which Christopher, (the protagonist), finds Wellington, Mrs Shear's dog dead with a fork stabbed through it at 12:07 PM. As visible, Christopher is greatly upset after finding the dead dog, hence picking it up and hugging it, while Mrs Shear's comes out of her house infuriated, hence screaming at Christopher.
In continuation to the previous scene, Christopher had been arrested after punching the police officer who had arrived at the scene and of suspected murder of the dog. After having his father arrive, Christopher is then interrogated. As visible, both Christopher and his father are frustrated while the inspector questions the truth of his answer.
Lastly, within this scene, Christopher is keen on investigating who killed Wellington, and as a result proceeds to go around his neighbourhood, hence asking others (specifically those he suspects) whether they know any information. It is visible that his suspects are greatly confused, uncomfortable and slightly angry because of his suspicions.
