DW question, surprisingly enough not about D/R (WOW!)

[mrv3000]

Was just thinking about this. And yes, random thoughts tend to make their way to LJ. So, I think it's pretty much Generally Accepted Who (aka fanon) that the regeneration from Eight to Nine happened during the Time War. Whatever it was that the Doctor did to end it all (which is canon - he pushed the button, so to speak, per Sound of Drums) was so catastrophic, that it caused him to regenerate.

But...has it actually ever been *said* in canon that he regenerated due to this specific event? Did they say something in Sound of Drums/LotTL that I'm forgetting? I think I always have it in my mind that Eight was the one to go through the Time War. Could it have been Nine instead? Possibly due to an early battle in the Time War? (He mentioned he fought on the front line.) Or maybe even something that happened before the Time War?

This isn't for some kind of fic or anything. I'm just kinda curious at the moment.

ETA: WOW. I totally need to watch S1 again. In "Rose" he's checking out his ears, so it had to have just happened.

And this makes for my second moronic post this week...

*headdesk*

ETA2: And...you could still question the whole "regeneration due to Time War" thing in a way I hadn't thought of. Nifty!
