Squire Western arrives at Squire Allworthy's house just after breakfast.
Poor Squire Allworthy has just been feeling good about the world.
So you can imagine that he's a bit surprised when Squire Western shouts out of the blue, "You have brought up your bastard to a fine purpose" (6.10.2).
Squire Western screams that Tom has been "poaching after" (6.10.2) his daughter.
Squire Western plans to lock up Sophia and make her marry Mr. Blifil.
He runs back out of the house as suddenly as he came, afraid that his daughter will try to run away while his back is turned.
Mr. Blifil is furious.
He doesn't care about Sophia at all.
But he really doesn't want Tom to beat him in her affections.
Mr. Blifil jumps at the opportunity to badmouth Tom to Squire Allworthy.
He tells Squire Allworthy about the fight between Tom and Misters Blifil and Thwackum
He says that Tom attacked him and Mr. Thwackum unfairly (see Book 5, Chapter 11 for the real story).
Squire Allworthy brings in Mr. Thwackum and asks if this is all true.
Mr. Thwackum arrives and (of course) backs up everything terrible that Mr. Blifil says about Tom, the fight, and its causes.
