Once we have watched the entirety of a companion's run we will add the companion to these rankings. We are each using our own internal standards to determine who makes the list and, as usual, we disagree on the standards.
Clay's Companion Rankings
People who just missed the cut: Currently everyone is on the list!
River Song, who I think should not be on a companion list due to being "more than a companion" is currently on the list at #7.
My list is also extremely fluid and can and will change at any time.
Stephen's Companion Rankings
My criteria to determine "What is a companion?" is extremely vast, inconsistent, and illogical. As such, I've decided to include everyone who I feel deserves that ranking of which I've seen their entire run. If you'd like to know why I include certain people, I'm happy to discuss it unless I'm not.
In addition, my list is fluid and as such can, will and has changed order depending on personal mood fluctuation, epiphanies and discussions with other people.
