Last week I made a very simple prediction about this week's episode: that the Blake reference will not be just in the episode's title, but explicitly articulated by the characters.

And sure enough, we learn about the "Blake Organization".

Why is this significant?
Up until now there was only the poem "Tyger Tyger" as a definite inside-the-show reference to Blake.
Yes, Bertram quoted "A Cradle Song" at the end of "Red Queen", but that could be random.

But now we know that Blake references are significant - they are messages from RJ, rather than an artistic device by the writers of the show.
There's only one message that is more incriminatory than Bertram's quotation, and that's someone having such a reference as their alias.
Yes, "A Brace of Partridge", I'm looking at you.

I'm not going into the whole "he's dead" argument.
Suffice to say that even in this week's episode, Cho does not take a look at BP's face.
What amazing storytelling!

And now for the punch.

There's one more character with a Blake reference for an alias (and we know it's an alias rather than a real name).
Can you guess who?

Tamzin Dove. Remember her?
Tamzin = twin = pair = brace
Dove = bird = Partridge (yes, quite different birds, but this is art, not ornithology!)

Is Tamzin Dove RJ's daughter?
Will she follow in his footsteps after PJ kills him?

Tamzin Dove is portrayed by actress Azura Skye.
The episode following "Red John" is "My Blue Heaven".
Fill in the blanks.
