Didn't the seventh Doctor trick Davros into killing himself? I think it was Remembrance of the Daleks.

Not that this has ever stopped a Doctor Who villain from returning, mind.

The Master was also killed many times in the old series and the Daleks have been wiped out from existence about a dozen of times now. I don't think death would be enough to keep Davros out of the way.

It could be an alternate dimension Davros also.

Well, the master was a time lord, wasn't he? And the Darleks are a race, rather than just one guy who was (I'm guessing) killed onscreen. I think they'll drop the darleks for the major plot of this season, which is to say that I think they'll be an episode or two around the darleks (wasn't there one left?) but no, I don't think it will be the big finale or anything important enough to include Davros.

He was a Time Lord, but he actually went out through all his regenerations. During the eighties his whole plot was that he needed to get a new cycle of regenerations, "dying" many many times but returning in the next episode exactly in the same body as before. He died again, permanently, in the TV Movie. In fact, I believe he even said he was "revived" by the Time Lords in the last season's finale.

All I'm saying is that anything can be retconned very easily in this series.

He's come back almost as many times previously. Actually, now that I recall Remembrance, I think Davros was spirited away under mysterious circumstances. I don't think he'd have been in the Void though. The Daleks don't like him.

I doubt Davros is even coming back anyway, the Sontarans are the Big Bad this season I believe.

Oh and I had a look, but it doesn't appear the Barrowman is in next weeks episode. A missed opportunity there.

Well, he doesn't have to be the season finale to be in it. They're probably trying not to do another Dalek focused finale.

What are the chances that they start selling the things from the first episode this year? Even as a blokey-bloke, I wanted one.

As far as I remember the Time Lords gave him a new cycle of regenerations to help the Doctor in the Five Doctors and then after he died again resurrected him to fight against the Daleks in the Time War.
If the Time Lords can just give out new cycles of regeneration why do they ever die?

I imagine that regeneration limit is something imposed to prevent them from getting too powerful or immoral, as an eternal being would totally get. Stretching it would only be in dire circumstances, lest they create a monster.
