omg I just compared the number of companions for each Doctor and then I saw ten’s got more than eleven and then I thought “but eleven still has time for more companions” and then I realized hE DOESN’T BECAUSE HE ALREADY REGENERATED WHEN DID THIS HAPPEN
grace seems to have murdered all the eighth doctor companions
Tried to make this a little more complete (although there may well still be gaps) as well as trying to keep it to characters who had more than one story with the Doctors in question. :P
