Ninth Doctor (The Curse of Fatal Death)

An incarnation of the Doctor was glimpsed when the Eighth Doctor looked into the Tomorrow Windows. The Eighth Doctor described him and his female companion as "a listless-looking man [who] sat on a sofa beside a girl in a red dress in an unconvincing medieval dungeon". (PROSE: The Tomorrow Windows)

Behind the scenes

 * This is a clear reference to Rowan Atkinson's Ninth Doctor from The Curse of Fatal Death; his companion in the red dress is Emma.


 * Although the specific mention of "ears" as the new Doctor is feeling his face suggests Christopher Eccleston's Ninth Doctor, Doctor Who and the Time War does not positively identify the Doctor into whom the Eighth Doctor turns. Echoing The Tomorrow Windows's in-universe confirmation that the Doctor would somehow have "three ninth incarnations", Russell T Davies answered affirmatively to a comment by a fan on the Instagram release of Doctor Who and the Time War suggesting that—"…the Ninth Doctor here could also be interpreted as the Shalka Doctor or the Rowan Atkinson Doctor for the hat trick of alternative Ninth Doctors."

- (source) This followed Davies' earlier comments that clarified Doctor Who and the Time War's position in relation to The Night of the Doctor as a "glimpse of parallel events" and his broader statement upon its release that "all Doctors exist [and] all stories are true".
