Secret Informant

ASK FANTASY FLIGHT 

Q: If you have two Secret Informants participating in an engagement, how many times can you resolve a Fate card from your edge stack? If Twist of Fate is played, does it resolve additional times?

A: If you have 2 of them in an engagement, you would resolve each Fate card you reveal 3 times.

The first time you resolve Twist of Fate, it will cancel the edge battle, closing the window of opportunity for resolving the card a second time.
