Granger takes Moody's arm and Apparates to a sunlit location with a lake, some tall grass, and trees.
Moody's speech is drawn in a very rough style, and is much darker than Granger's.
MOODY: Where are we?
PAST GRANGER: The first thing I did after I learned to Apparate was to find and memorize eighteen remote locations to use as escape routes. Now that you've seen this one, I have seventeen left. I picked them using dice and a map of Britain, so there's no way for anyone else to guess where I would have picked.
MOODY: Useful. But what will you do if your enemy grabs you before you can Disapparate?
PAST GRANGER: I've equipped two locations with traps for anyone who follows me.
MOODY: So you could have taken me into a trap. Good. Right then. You had a favor to ask. One that requires a moderate level of security.
PAST GRANGER: I want you to use the Cruciatus Curse on me. If I'm going to face it, and my fellow Aurors are going to face it, I need to know what it's like to be hit by it.
PRESENT GRANGER: Or so I rationalized it to myself. What did I expect to accomplish? Would putting myself through this somehow change what had happened? Or was it simply the most convenient way to assuage a sense of suvivor's guilt? Do I know myself well enough to be sure?
Granger may be second-guessing zemself here, but to Moody, that explanation seemed perfectly sensible and logical!
This was obviously before Granger instituted the policy about saying
Torture Curse instead of
Granger also has escape locations outside of Britain, but there's a limit to how far you can Apparate, so those locations are only relevant while Granger is travelling to other countries.
One thing that I left out of this page was to have Granger and Moody confirm each other's identities before leaving the Ministry. It would have added to the
Moody is totally serious about security, and so is Granger thing, but I couldn't come up with a good way to do it. They could have security questions, but it's hard to come up with shared information that can't also be guessed by someone who's been planning to impersonate you, and the bigger threat is if the person is under the Imperius Curse (Can the curse force someone to give the proper answer to a question? I'd guess that it can). The real Granger can resist the Imperius Curse, but it wouldn't be Moody's style to trust in that.
The only clever solution I came up with was for the two parties to make an Unbreakable Vow that they would truthfully reveal their identity and whether they're acting of their own free will. However, if that style of thing worked, people could use Unbreakable Vows for all kinds of things, which would change a lot of stuff about society in unexpected ways. So I figure there must be some major additional restrictions on the Vow that make it undesirable for general use. (Also, it requires a third person.)
