Setting: Old beat up houses with junk in the yards with rusty metal fences around the property.
Bodoni is caring and thoughtful. Some evidence to support Bodni being caring is "From a broom he broke off straws of various lengths. The shortest wins." And evidence to support him being thoughtful is " But I am a great fool. I will take the money out of my bank and give it to you."
Bramante is negative and deceiving. Some evidence to support him being negative is "what a senseless task you will set you boys to". And an evidence of him being decieving is when he said "you would think of throwing her in the river."
Foil is a character who contrasts with another character, that is usually the protagonist, to highlight qualities of the other character.
These traits can be found in many different quotes and in the way he talks.
The traits above are found in the beginning of the story when he was talking to Bodoni. Bodoni talks to him in about how he wants to go to space. And Bramante uses a mean tone and puts a bunch of weird thoughts in his head.
