Who are these Guardians? (From someone not familiar with the Expanded Universe, Big Finish, or other additions to the Whoniverse.)

this was so sad, and so good. i loved the brigader so much, despite him being before my time. i have gone back and watched a few of his, and his appearance in SJA.

That was a great tribute to great character and an respeccted actor. I haven't seen all of episodes that Alistor was in, but the ones I saw I liked him and how he was with dealing with the Doctor.

To bad the actor couldn'lt have reprised he's role either before or in later shows...

Great job!
