Waitwaitwaitwaitwait, I thought half the point of this was to mend the wall, not break it!
Well I think it’s understandable that people are curious as to what would happen if the wall WERE broken completely. We’re human, that’s kind of what we do: we wonder, we theorise, we open Pandora’s box even though we know from experience what a bad idea that is. We also know from experience that sometimes the greatest goods come from horrible things (although granted more
horrible things come from horrible things that good ones...).
Still I don’t think I’m cool with the idea of us making the Wall worse, at least not deliberately. No matter how curious I am, I don’t want to be party to what could be an extremely dangerous and irresponsible action,
just because I want my own sonic screwdriver. I don't think it'd be worth the price paid, guys.
As for the letters, the first was a warning and the second was a threat. Even if some had been from the "good guys", he probably wouldn't read them yet until he felt safe enough.
I agree, while I'm willing to consider that hey MIGHT turn out to be good guys (at least some of them), and I think Joe needs to investigate that side of things further, they have gone about it in a bad way. They began all this with a campaign of intimidation, and with being threatening and vague. If they’re the good guys in all this why not be honest and tell Joe what the deal is, instead of just working on scaring the bejeezus out of him and making us more determined not to stop? They’re behaving in exactly the same way Mister A is – demanding actions from us without giving us any explanation.
Maybe we need to arrange some way of MEETING with these fictional guys in person. Find out from them what it is they fear so much. I don't want us all to be enemies if we don't need to be.
