I was going to have my say on Planet of The Dead, but I'm too lazy. It'll have to wait until tomorrow or something. Instead, have a list of Who companions from Other Times and Places vs. those from Contemporary Times and/or Places, i.e. whatever decade it was when said companions made their appearances. Mostly to dissprove the notion that the companion needs to ''root'' (thanks to
lizbee , I can never again take that word seriously) the Doctor by being from London in ''our'' time.
From OTAP:
Susan ''Foreman'' (Time Lady*, Gallifrey, Rassilon Era)

* It's been speculated if she's only an ''ordinary'' Gallifreyan with no ability to regenerate. I'll presume she's a Time Lady unless proven otherwise.
** He was working in the US when he met the Doctor but, you know. Maybe I should've placed him among the contemporaries but he is from the future, relative to us, though only the near one.
*** She stated in Pyramids of Mars (?) that she was from 1980, leading to confusion about when Three's and part of Four's era actually takes place.
So, that's 17 companions from another time/and or world and 18 contemporary ones. Split almost perfectly even, although companions being from London is hardly new. I might've left out someone. I deliberately left out companions from the audios, etc.
