You won't have to worry about that, Darin's not adept enough with his abilities to pour on the damage like that. A few solid shots, definitely but he's far and away from being able to take down an Eikon solo.

I actually have the same image in my head! As for how the whole thing kicks off, I was thinking it over. Darin would probably try and bail at first because his first inclination would be to not get involved. But if Garuda went after an innocent bystander, he'd leap in to fight her off without thinking. How does that sound to you?
