Query: Whose on Who

I haven't had cable for a while so I've missed about a season and a half of Doctor Who. A friend told me of this Special and I hurriedly ordered it on Amazon Prime. Some characters from episodes in the past are in this show, as is someone else who is new. Now I have to backtrack and see what has been taking place. Not a problem as almost all episodes of Doctor Who are imaginative and entertaining and mystifying. This one was excellent.
