Hello, I’m an entirely new member, in fact I actually only signed up to post this post (though I’ll probably stick around) because something about the Doctor’s accent struck me. I write a lot of fanfic on A03 (DBC_82 if anyone is interested) and I was trying to think of a legitimate reason as to why the Seventh Doctor was Scottish and it got me on to the wider reasoning of the accents of the Doctor.
I seem to remember reading about a deleted scene where the Tenth Doctor explains he’s imprinted on Rose and that’s why he sounds a bit like her, and by the extension of that why later Doctor’s sound the way they do and it sort of broke my heart. So…
11 – regenerates alone on the TARDIS and so generally sounds sort of accent neutral but spends the majority of his time with Amy Pond (who obvs is Scottish) to the point where her hallucination/memory is one of the last things he sees before regenerating into Peter Capaldi, who is Scottish! Could it be that memory of Amy was what triggered the change in 12? Anyway…
12 – spends almost his entire time with Clara who is so significant to him that he’s literally willing to follow her to hell until he forgets her entirely. And then when the Testimony restores his memories of the most important person in that Doctor’s life he then regenerates into a woman!
Obvs this goes no way towards addressing my original query as to why the Seventh Doctor suddenly adopted a Scottish accent after 953 years but I wanted to share my thoughts even if they’ve probably already been expressed 🙂
