Howling:Regeneration, ressurection, The Eye of Harmony, and what happens after 13.

1. We are talking about a race billions of years old. How do you put "checks and balances" on an "immortal" race that very well could last until the end of the universe? For this reason, I purpose that the regeneration limit was political and not biological.

2. These limits were enforced by the matrix on Gallifrey. This served as a repository for all time lord knowlege and sentience. The matrix had a biological imprint of every time lord that ever has, or will, exist. After the 13th "death" the matrix would accept the atrion energy that formed the time lords "soul" (for lack of better term) everything the time lord ever was would have been deposited into the matrix. When the Master finally "died", this is where the time lords would have had to gone to resurrect him.

3. I was surprised to actually see the eye of harmony on board the Tardis. Now we have 3 different examples of the eye represented on Doctor Who. One is a gigantic crystal on Galifrey, one in the TV movie, and now one here, in "Journey to the Center of the Tardis". At first I thought the Doctors Tardis was mainlined into the eye on Gallifrey, like an extreme ultimate speed internet connection. When Gallifrey was cut off, the power source for the Tardis was cut off, and he had to refuel at rifts like the one where Torchwood was stationed. I wonder if this is the star that went nova when he spoke to Rose when she was marooned in the other universe, captured and used to re-create the eye so he would no longer be vulnerable during these "pit stops"?

4. So if he is cut of from the eye on Gallifrey, it would make sense that he is cut off from the matrix as well. As long as this remains true, he can regenerate an unlimited amount of times, as long as his connection to the matrix is NEVER restored. The master disconnected himself from the matrix when he (possessed?) Nyssa’s father. The matrix would no longer be able to bind him to rejoin it upon death since now he has altered his biology. Since Nyssa’s father could not regenerate, neither could the Master. (In the classic series anyway)

5. It is also possible that the in TV movie when the Doctor was on route to Gallifrey with the Masters remains; the purpose for this was to re-integrate him into the matrix. If this happened, then it would have been possible to pull him back out, resurrect him as a new time lord with a new set of regenerations for the TV series.

6. So as long as Gallifrey remains time locked, the Doctor can regenerate as long as he wishes. If Gallifrey becomes free and returns to the land of cause and effect, the Doctors regeneration cycles could restart with his current incarnation being equivalent to his first. This could open new character development as the Doctor gives up his immortality to bring back his people.
