Sam will recover from the ability drain faster, as Kasumi will Empathic Transfer the ability damage, then he can heal that damage in her.  Kasumi would like both the Ring and the Amulet, but will not ask for dibs, and only buy them if no one else does first.<br/>Sam could help here by taking 10 on Diplomacy to give Kasumi a +2 to her diplomacy check with the boy.  :)  And keep Saithe from terrorizing him again.
