You know, he's probably just gonna forget the memory when the mind-wipe spell hits him again.
If we somehow manage to restrain him we can try telling him the story fifty times and seeing what happens. GOD that would be weird.
I respect that, but at the same time, us making a long multi-step plan has the potential to

I strongly suspect Yammar CAN put up a mind shield capable of just plain blocking out any message we care to send. That seems to be a thing you can do with Mind Delve or Telepathy.
