The rules say spent fate cards go in the discard pile but: For Greivous, when he kills a Jedi, the rules mean they 'come back to life's when the Fate discard is resuffled, yeah? We house ruled that when a Jedi is defeated - into the box instead. It makes sense thematically and also, in our opinion, having dead Jedi reappear also makes Greivous' win condition easier (too) to achieve.
