Okay, I get it, there's not much to spoil here, it's just a bunch of diary entries and not all of them flow well with the ones before it. Not ALL of them, at least.
But, in case you haven't read the Master's diary yet, he tries to admit that he's scared of the Doctor, but he can't. So FUNNY! It goes something like this:
"The Doctor . . . the Doctor . . . the Doctor scares . . . the Doctor . . . the Doctor scares - UGH! Whatever! If you tell ANYONE about this, you will PAY!"
That's not exactly word for word, just how I remember it. It's funnier if you read the whole thing anyway. So. . . PLEASE READ IT!
Also, if you haven't read Amy's, Rory's, or River's . . . they are SO funny. They argue over EVERYTHING!
You really REALLY need to read this, but I haven't edited it in awhile, so you might have to search it.
