In order to attack an enemy with Impersonation, does the attacking character have to have LoF to all other characters, or do all other characters have to have LoF to the Impersonator? And what about allies?
Thematically the first make more sense. The Impersonator will change it's looks to somebody not in your eyeside. When you can compare the two, you can make the distinction. - "Targeting this Enemy for an Action in Range 3 or more while they has the green marker requires having Line of Sight to every non-Remote Character" (I think they mean 'they have' or 'it has') - "For all intents and purposes, an Ally is a Character." So yes, including allies. Even Neutral Characters as I read it. Impersonator will never look like a remote apparently.
