We've been running a custom campaign for a while now, about once a month for a little over a year. For one of the players this is the first real extended RPG campaign. He is playing a guy who found a magic amulet in an ancient South American ruin that is the conduit to a god-like panther being. Think Moon Knight, with a different motif, and he turns into a giant panther instead of gaining suit.
So, last night I put my players in a situation where they were arriving at the scene of police beset by supers. They arrive and start engaging the supers to save the police. But, in the classic switch, they aren't real police - they're AIM in disguise chasing down these super experiments who escaped from a secret lab. My players do not hesitate and dive in to engage the supers endangering the city. The fight is getting serious, and it looks like one or more of them may go down when more heavily equipped AIM figures reveal themselves fully 'too early' with undisguised agents arriving so the overwhelmed "police" can retreat.
So this newer player is among the first to realize it could be mistaken identity... and then unprompted, for the first time at our table he asks if he can reach inside and ask his panther patron to help make sure they are fighting the right people.
I was completely unprepared, but was so proud of the role playing moment. For the entire campaign he's never initiated 'contact'. I gave him a quick Ego roll to contact his patron to seek guidance, we played out a fast convo... and I let him tell the rest of the team what he believed, and they flipped the entire battle as they teamed up to wipe AIM. It was glorious.
