AU where rose gets shot by the dalek instead of the doctor and she survives long enough to be brought back to the tardis and he's saying he can fix this, he can fix this, he can fix this. and rose says it was worth it (it was.) and when she stops breathing the doctor just. stops. period. so so still. frozen over her.
and i think it takes just long enough for jack to get close and take her hand. because he needs to. before it goes cold, he needs to.
