Fine then. Let Mo have the stone cause the ritual was still very cool. (I did forget to mention that didn't I?)
Let's say Martin took the deal Mithias gave him when he was locked up.
They locked him up anyway to give to Magnus to play with, see if he can dig any other info out of him.
That way no post have to be edited and we can get this show on the road.
They wouldn't be in a hurry with the mind digging, let Martin stew for a while.
