SW - I haven't read the rest of the thread so may be repeating others but just thank them very kindly for their offer of a meeting but you're ok at the moment. Tell them you know where they are if you need them.
Don't get drawn in to debate, express doubts, challenge doctrine or any of that shit. Just keep your head down and your mouth shut and they'll stop bothering you.
They need a reason to form a JC - don't give them one.
Good luck!
