Welcome to the Official Redemption® Message Board!
The card says if the rescuing player doesn't have the most redeemed souls he can make another RA.
There's a big difference between having the least and not having the most.
Assuming you are the one who started the RA. (Remember, this card can be used defensively as well.)
It's semantics... does "the most" mean "the greatest number" or "more than everyone else."
Those cards state their meaning though. Grapes does not.
