Sam Wilson's Ld states 'when this character or an allied character is Dazed or KO'd, choose another non-Dazed allied character. The chosen character removes 1 wound, removes one special condition, and may advance S. A character can be affected by this leadership only once per round'. In the following scenario what happens:
There are 3 characters. Character 1 has already been affected by the Ld when character 2 is Dazed - do you have to choose character 3 to be the recipient of the Ld? Or if you don't move/heal etc. do you count as not being affected?
This matters because in the case of Field Dressing, character 3 may get another opportunity to use the Ld which they would be ineligible for if they had already been chosen because it is a must.
