(AI) Mistress Alphys in a TARDIS

I find it just a little weird that whenever I choose to give a prompt of Mistress Alphys in a TARDIS, it seems that I'll get a random assortment of machine parts with a vortex background, a completely original TARDIS interior design or a design very close to the 11th/12th Doctor's TARDIS interior. Never any other Doctor's TARDIS interior or even a Master's TARDIS interior; although, those tend to be just darker coloured versions of the Doctor's TARDIS interior anyway.
