The announcements and media coverage for Hornets' Nest all describe Yates as the Fourth Doctor's companion, so I think adding him to the list is justified. 23skidoo 05:23, 3 August 2009 (UTC)
K9 Mark III Edit
Prior to switchover to new format, template maintained that K9 Mark III was a prose companion of the Fourth Doctor. What's the source of this?

There should be a "Single-adventure" slot for Spandrell, Engin, Henry Gordon Jago, George Litefoot, Tegan Jovanka and Nyssa.Tirenifs talk to me 12:13, February 13, 2012 (UTC)
Plus, Brigadier Alistair Gordon Lethbridge-Stewart and John Benton should be added due to Robot, Terror of the Zygons and The Android Invasion.Tirenifs talk to me 12:13, February 13, 2012 (UTC)
