I don’t think either approach is bad but there’s a certain irony in RTD era companions travelling full time with The Doctor but the audience sees their families a lot, but Moffat’s companions travel part time but the audience hardly sees their family.
want to be clear that if i ever talk about a headcanon and then later discuss a headcanon that is directly contradictory to the first one, that’s because headcanons exist in a quantum state where they are all simultaneously true and not true up until the point where i discuss it in detail, in which case that is the one that is true in that instance. schroedinger’s headcanons
that’s what characters ARE. not people, but potential. many things, as needed, no matter how mutually exclusive.
