The Charger quest(again)?Follow

Helped a paladin out in dire maul on my druid and he got his blessed barding. Can anyone tell me though - if another paladin has already done the quest and has the divination scryer. Would the the other paladin be able to loot the chargers redeemed soul off the deathknight? Or would they still have to buy both the diamonds before getting a scryer themselves?

Darn. He will have to find or buy the diamonds then, suppose that gives me some time to myself while he grinds for cash. Thanks for the reply!
