I can’t believe the jokes that 13 will be bad at parking when 10’s introduction was him crashing the TARDIS into several buidlings
Can you write a soulmate AU with the first words your soulmate says to you (original, I know) for Rose and 10? The twist is that the Doctor has the first words Rose says to him but she doesn't have 9's for her but 10's, so 9 is constantly sad and frustrated when she flirts with Mickey or Adam or Jack. That's also why he is so devasted when he thinks she's dead and why she looks so shocked when he becomes 10. I would write it myself but I literally have no writing skills for fictional texts.
