extra dice- when to add & remove

[ebill1]

in my last game the witch king was killed in battle, & we were not sure when to remove the extra shadow die that had been added. for the record (since i can't find the exact procedure in the rules):
1. when a companion is upgaded or minion added due to action dice play in a turn does that player receive an extra die starting the next turn- i assume so.
2. when aragorn, gandalf the white, or any minion dies in battle when is the extra die removed from the game?
does it happen on the next turn (our guess) or immediately; & who chooses what die?

The extra die is added to the pool of action dice the following turn.

If a Character dies his extra action die is removed immediately, preferably by removing an already used action die.

But if no die has been used that turn the player controling the now dead character must choose one unused die.

All Eye dice in the Hunt box are "in use" so they can't be choosen if a Minon dies.

UPDATE!

The dice pool is not affected untill the following turn so the lost die is removed just before the next turn begins.
