Dr Who Empire of Death Alternate ending Sutekh vs Bad Wolf (see description for details)

So my editing skills are limited, but this is how I envisioned this alternative ending.

Rose has a teenage pregnancy, which she hides from everyone, including her mum, abandoning her daughter in 2004, one year before she meets the Doctor.

When she looks into the TARDIS and becomes bad wolf, she comes to know of Sutekh and his clinging to the TARDIS. They battle throughout time and space, with Sutekh trying to cause chaos and death and Bad Wolf trying to protect the Doctor. This could explain why the TARDIS sometimes landed the doctor in danger and sometimes would land him in the right place at the right time - representing this power struggle.

However, when the TARDIS split into two, this was the triggering event for Sutekh to break free from bad wolf by having his “own” TARDIS, giving rise to the TARDIS groan from blue yonder onwards.

In my version, Bad Wolf is the one that spreads Susan Twist throughout time and space, but it is Sutekh who tries to use this against the doctor and corrupt the Susan twists, which he succeeds in doing once he gains power from the Tardis split.

Bad wolf blocked out the memory of her daughter to protect her from Sutekh, so much so that Sutekh, nor anyone else could tell that she was Ruby’s parent. In order to do that, she manipulated her own timeline to end up in a parallel world where she could not be found (events of Journey’s end).

However, the events of the two part finale and Ruby gaining more and more knowledge, combined with Sutekh’s rise in power, trigger bad wolf to return once Sutekh is made aware of Ruby’s parentage.

Bad Wolf then returns for an epic battle with Sutekh across time and space (unfortunately I couldn’t do it justice with editing) where eventually she destroys Sutekh and brings back life to everyone else, but in doing so destroys herself and tragically never gets to meet Ruby.

However, in one last action before Bad Wolf perishes, she brings her past self in the parallel world (say a few years after journey’s end) along with her family and the meta crisis doctor to this world, where she is able to reunite with her daughter, and has an astonished interaction with the doctor seeing his new regeneration.
