Flip Flop

All right....I'm going to attempt to understand this one. Here goes:
I listened to the Black disc first. Once I was done with the White disc I wanted to go back and listen to it all again in order to fully understand the story, but I was afraid my head might explode from trying to understand this audio. At first I thought it was like a spiral, looping downwards, but then I realised that it's actually a figure eight: the story goes in a circle on one world and then switches over the other world where it completes another circle, and vice-versa if you listen to it in a different order. But how was it that there were two Mels and two Doctors coming in from the same point in time? Why was it different? I have a theory here, or rather two theories: The first one is that there are two universes, both created when Stewart and Reed went to kill the President. It was a decision, and decisions create universes. One decision was to let the president live, and one was to kill her. This sort of explains why there are two different Mels and two different Doctors who are coming from the same situation (the Quarks on the spaceship). My second theory actually makes more sense, and is even more clever on Johnny Morris's part. There are actually two different stories going on, not one continuous one. The Black disc is one story, and the White disc is the other. The main focus of each story is Stewart and Reed and their involvement with the assassination attempt. Whew. Usually I love Johnathan Morris, he's done some fantastic novels and audios, and deserves to write a TV episode. But this story just seemed too confusing.
Other notes:

• Recently I read a description of Mel saying that she was "bossy and practical", and I thought to myself: what a good way to sum up her character. I wouldn't have chosen those adjectives myself, but considering her Big Finish stories and the best of her character in TV episodes, those are really the best ways to describe Melanie Bush. No screaming for this Mel: she's all morals and asking the right questions and respecting the Doctor, but at the same time taking absolutely none of his bullcrap.
• The way the Slithigees feigned helplessness when they, in effect, ruled the world was absolutely terrifying. Yes, they were blind, and yes, they seemed polite, but boy did they get people to do anything they wanted.
• The Doctor says at the end of both discs that the other Doctor and Mel will fix things, but that means that nobody does. And how could he? Pauxataunee is pretty much beyond help, and short of blowing up the fleet before they arrive 30 years previous, I can't think of anything any of the Doctors could have done to save the day. How bleak.
• Yes, that was a sex scene. Moving on...
• Another Christmas-time story! That brings the list up to:
• Chimes of Midnight
• Winter for the Adept
• The One Doctor
• Voyage to Venus (okay, so they sing a Christmas carol. It counts.)
• Flip Flop
• Big Finish doesn't usually physically or mentally torture Seven (they save that for Five and Six)--heck, I don't think he ever gets tied up. So the way that wonderfully creepy Professor Capra tortured him and Mel was surprising and rather scary.

All in all, an extremely confusing audio. Someday, I plan to make a color-coded chart for both this audio and The Kingmaker. If you are not paying absolute attention and possibly taking notes, you will get very frustrated by trying to understand it. I recommend a re-listen. If your head doesn't explode.
