Remember the Fallen rulings:
2011-06-01: You choose which mode you're using — or whether to use both modes — as you're casting the spell. Once this choice is made, it can't be changed later while the spell is on the stack.
2011-06-01: If you choose both modes, and only one of the targeted cards is still a legal target when Remember the Fallen tries to resolve, only that card is returned to your hand.
