Lord Everard did not show any signs of panic even after confirming from Godric that only the Eighth stage Sovereign captured by Grey can deal with his strange movement technique. For someone on his level, he did not believe there was no way four Ninth stage Sovereigns and about five Eighth stage Sovereigns can not deal with a single Seventh stage Sovereign. No matter how heaven-defying Grey's abilities were, he was not invincible.
Although Grey's act of apprehending the Eighth stage Sovereign since he counters his technique was amazing, it showed Lord Everard something, and that was that Grey is not untouchable as he or Godric is making it out to be.
'Since he can deal with his strange movement ability, I don't believe none of us here will not be able to stop him.'
