After Eliana's death, Firo's going to focus on talking to off-duty dealers at the casino, starting off with more small talky "wow, that's awful" and trying to feel out their general reactions. He'll try to steer questions more towards anything suspicious in the area recently, whether that's guard activity or strangers like the Circle.

He'll also try to see if any of the pickpocket kids hanging around the market will talk to him in return for some money. He's not going to bother being subtle about it with them and will point blank ask what they know about the area of the murder and what they saw the day of. Would he find anything out from these?
