Theory:Timeline - Clyde Langer

This page lists appearances of Luke Smith in the order he experienced them. This timeline is based upon observations of the Doctor Who universe and the events that occur during each of these stories. From these observations we have attempted to build a concise timeline. It is assumed that for each novel, comic, audio or television series, their published, broadcast or numbered order is the order they occur in.

Fan sources like the Doctor Who Reference Guide should not be used solely as a source or considered a "true" timeline for stories.
