In all honesty I suppose we can try to give the bigwigs a shot at direct negotiations with us, but I really fucking doubt that'll go anywhere. At least, not anywhere that we want it to go. In which case, the tacked on "I've been playing nice so far, so don't test me" clause most of those votes have will likely come into play; meaning things going boom regardless. I guess that it has being the polite thing to do before wrecking their shit in going for it.
Frankly, if people wanted to play nice and diplomatic they should've tried to...you know, be honest and upfront with the TSAB right from the get-go. Instead the whole 'keep everything hidden' plan got pushed and when Flandre's unstable ass went...well, unstable; shit hit the fan. Granted, the fairly out of nowhere third persona asspull rankled a bit, but really it was gonna happen sooner or later.
They saw our little escapades in PMMM land, there's really no way for them to assume anything good about us; with how casually we caused chaos and mayhem in that world. As well as how unstable we are and how easy we are to trigger off, as the illusionist who pulled the fake Remilia served as a wonderful example of. At best we'll always be a rabid animal on a leash, a very short and tightly held leash at that.
