When Ethan Thompson entered, what he saw was this scene: several sheets of A4 paper slipping off Phoebe Smith's face, Joseph Thompson with a mottled face, Phoebe with a flushed face, while Susanna Smith stood by with a pale face.
Blue, red, white – three faces that represented their emotions at the moment! Anger! Fury! Guilt!
Phoebe Smith was the first to notice Ethan's entrance and immediately ran up to him, "Uncle-in-law, you're finally here. My second brother bullied my aunt-in-law, and he just knocked me down."
Ethan Thompson adored his daughter and because Susanna Smith's daughter died at birth years ago, he treated Phoebe Smith exceptionally well when she came to live with them as a way to make it up to Susanna.
In Phoebe's heart, her uncle treated her as any other father would treat their daughter, so upon seeing Ethan Thompson, she immediately began to coquettishly accuse Joseph Thompson of his recent misdeeds.
