"Action in Exile" is a significant story in the history of early Doctor Who comics. It marks an overt sea-change in the tone of TV Comic strips, for two reasons. It is perhaps the first time that the strip incorporated on-screen continuity into its stories. And what was acknowledged — the fact that the Doctor was exiled to Earth, but that we didn't actually see the consequent regeneration — allows for the final Troughton stories to be firmly set in what Doctor Who fans sometimes call "Season 6b". In other words, every story from here to "The Night Walkers" is set between the last televised Second Doctor story and the first televised Third Doctor story.
Within the continuity of the strip itself, "Action in Exile" sets up a little whiff of a multi-story arc which concludes in the final installment of "The Night Walkers".
