Joey Potter, it’s great to have you back on TV. Katie Holmes, who will always be the girl from “Dawson’s Creek,” is returning to the small screen with a guest role on “Eli Stone.” “I went and begged her,” said Greg Berlanti, a former “Creek” producer who co-created “Stone,” a second-year ABC drama (in need of more viewers) which stars Jonny Lee Miller as a lawyer with prophetic powers. Holmes, who will also play a lawyer, appears in an October episode… and (hopefully) it may be a recurring role.
