User:SOTO/Forum Archive/The Panopticon/@comment-24070818-20131127190509/@comment-188432-20131128011048 John Simm is in the opening credits for The End of Time and he's not considered a companion. Sorry, there's not a 1:1 correlation between appearing in the opening credits and being a companion. Also, Billie Piper is listed as "with", so she's not quite in the same position as a companion — as, well, Jenna Coleman — is. She's quite clearly a featured guest star, not a companion. Another point: this episode doesn't even have title credits.
