There is now a more specified ruling that makes the Nightly actions quite precise (it is written in the rules-section in the beginning of the thread).
If there are two kills during a Night the EW will need to state which is the order of those kills (kill#1 and kill#2) to ease any confusion or situations where the result could be argued to and fro based on different interpretations of the actions.
The wizards knew this during last Night (the new ruling was not needed last Night though
).
Also if / when the Wizards will duel and thence leave the game the same rule applies to the remaining wolf-pack if there are four or more of them eg. they have two kills.
Keep on having fun!
