Catherine's mum (Doctor Who?)
From Tardis Wiki, the free Doctor Who reference
Catherine's mum and dad conveyed the message "Hello" to Catherine through the First Doctor as part of a long series of personal interactions from the Doctor that started when he began expressing good tidings to viewers at Christmas. Steven Taylor heavily disliked this and thought it should have been nipped in the bud then. (NOTVALID: Doctor Who? 144)
