Grady is the handler to Creme and Abernathy's Freelance Sheriff gig, and voluntarily helps in making sure the background details and collateral of their antics are handled. 

His father was a science officer in a House-owned laboratory for covert chemical agents meant to temporarily drive down property values to facilitate real estate takeovers, and risked his life escaping the organization. As a result, Grady resents the House but uses his family's knowledge and network in the organization to help out their primary rivals, especially once Abernathy and Creme pledge themselves to the Teambase.
