Louise Jameson, who played Fourth Doctor companion in 1978 and 1979, was tweeted this message by a fan:
“If the #DoctorWho 50th special(s) doesn’t feature at least one past Doctor I think I’ll genuinely cry.”
Jameson responded with this intriguing tweet:
“None of us knows yet what’s going on, just told to keep the days free. Mmmmmmmmm intriguing.”
We should – as with any news about Doctor Who‘s 50th Anniversary Special – take this with the usual pinch of salt – but could this be a clue?
