Mother's Younger Brother Timeline and Summary

We meet Mother's Younger Brother as he stands along the shoreline, dreaming of Evelyn Nesbit. She's in the news because of her beauty and the fact that her husband killed a famous architect over her.
Younger Brother follows Evelyn around town, eventually hiding in a room where she is being given a massage by Emma Goldman. He masturbates in the closet and then reveals himself to Evelyn.
Unsure how to deal with someone who has so much affection for her, Evelyn has an affair with Younger Brother, but breaks it off when she gets bored.
Younger Brother goes to the office of Emma Goldman's magazine, where she tells him to get over Evelyn and silly ideas about love.
When Coalhouse's car is vandalized, Younger Brother goes to see the car and is enraged. After the first attack, he goes to Coalhouse and joins the gang, promising that he'll make explosives. To fit in he shaves his head and wears blackface.
During the takeover of the Morgan Library, Younger Brother wires the building with explosives. He gets away with the rest of the gang (except Coalhouse) and heads to Mexico, where he participates in the Mexican Revolution and is killed in battle with the Mexican Army.
