Still Passionate and Confused

Yes, but my point is, if every TARDIS has one of those things (and we know at least two did) and every Time Lord at the end of his lives could therefore rewrite himself at whim as a standard lamp or something and then come back as a Time Lord with a dozen new-laid regenerations in the larder, then that would be viewed as cheating. So I don't think it does that. I preferred the book version, in which the thing that turned him human was dodgy tech he had to buy in a market somewhere. But then, I pretty much preferred the book version full stop.
