This short extract from “42”, lasting just over three-quarters of a minute, was shown at the end of the most recent edition of “Totally Doctor Who”. Designed to give you the collywobbles, it is slightly undermined by Martha’s mobile conversation with her Mother in which Elvis appears to be a password! It suggests the Doctor has tweaked his new companion’s phone, the way he did Rose’s in “The End of the World”!! Hopefully, this won’t dominate the episode but tension and claustrophobia will!!!
