Ten Speed. Who he is.

In the Good Apollo graphic novel, Ten Speed is the manifestation of the Writing Writer's evil thoughts in the form of a bicycle. Ten Speed tries to convince the Writer to kill off a character named Ambellina. Ambellina is a Prise who is sent to watch over the story's main character, Claudio Kilgannon. The Writer discovers that Ambellina is based on his own cheating ex-girlfriend, Miss Erica Court, and to get over her, he must kill off the Ambellina character.

"But are you going to kill her off?"
"It's not your decision. I love the character, she stays."
"Yeah, well the only thing love's done is put you in this position; I say kill her off!"
"Yeah, but you say a lot of things... and how does that work? You're a bicycle"
