– Oscar’s parents die in a house fire. He lives on the streets with a bunch of other ragamuffins and makes fun of the major.
– Eventually, he’s caught and sent to Motley Horde. His crimes include pickpocketing, at most.
– In the Motley Horse Oscar meets the Witches and is immediately attracted to Ferret. Oscar weasels his way to the Tower and tries to befriend the Witches, at first because he thinks they’d help him escape, but then genuinely gets attached to everyone. Ferret treats him as a cute plaything.
Oscar was meant to be the “protagonist” of the Motley Horde-focused subplots. We’d learn about that place and its inhabitants through his experience.
