In case people haven’t noticed, WHENEVER ANYONE BOARDS THE TARDIS THEIR LIVES REVOLVE AROUND THE DOCTOR. EVERYONE.
Um. There’s a bit of a difference between someone’s life being heavily influenced by the Doctor and EVERY SINGLE ASPECT OF THEIR PERSONALITY, THEIR WHOLE SKILL SET, THEIR CAREER, EVERY SIGNIFICANT DECISION THEY’VE MADE, EVERYTHING THAT HAS EVER SHAPED THEM AS A PERSON, relating back to the Doctor. There’s a difference between those two things.
