Thanks again DA.
Any chance that can be backed up with a rule? I only ask because if it gets brought up again I'd like to be able to show it to them in writing somewhere. And as much as I'd like to say your post IS writing, I can't really refer to it as law.
Sure! YS 106: "If you wish, you can allow another character to use the tag for an aspect you’ve discovered or introduced. This allows for some great set-up maneuvers in a fight; you can maneuver to place an aspect on a target, then pass the tag to an ally who attacks, using the advantage on his own roll. This can only be done, however, if it is reasonable that the advantage could be passed off."
Also, my previous comment about passing along a free tag to a villain - that's not actually legal. Passing along the Aspect, however, is: the villain will just need a Fate Point to activate it.
