And there’s a weakened Sil in front of him with no one else around strong enough to stop him if he wishes to take him out. Unless Minny is feeling better with renewed strength to fight him from killing Sil. Though he better not or Quinn will have a hay day making him pay!!
Why would Mundus stop Sul getting the God Slayer Crystal and not stop Russ, only thing I can think of is H's crystal is of far greater power than Pines. Also don't like the fact Mundus has suddenly just appeared after nearly all the threats have been dealt with thought he said to Quinn he couldn't/wouldn't interfere.
