Garvin accepted Keegan O'Neil into the gang on O'Neil's first day at the university.
Later, after having had too much to drink, Garvin led the Crazy Shoes in a shootout against rival gang the Mauve Shirts. During the shootout, O'Neil took the opportunity to kill Garvin when they were alone and under fire. He then assumed control of the gang. (Nietzsche's Soldiers 3)
