@Zwei, Mercer's drone has a pretty good bead on the alley, but doubling, tripling, etc. up will allow you to cover more territory. I'm not sure exactly what you want me to rule on? The conversation on the mage's duel will probably take a couple minutes, so you should be able to get all drones out no problem.
Spitfire pilots a Noizquito around the entrance to the VIP area only to find the door closed. If you're actively Piloting it, you can check out around the AC vents to see if any of them would allow the Noizquito to pass through. I think I'll run this as a 6 Threshold Perception test, considering that there a number of vents, and the Noizquito would need to get close to each one to see if it could get in. If you'd like to invest the time and attention into it, make a series of tests, dropping a die each time until you hit 6.
@Mal, good search on Ishkitini. Mercer finds that the horned owl is a Mentor Spirit sometimes chosen by Choctaw shamans. It's particularly common with combat mages.
Mercer could spot the butt of a Savalette Guardian anywhere. She doesn't look happy to be there, but she's holding it together pretty well. The way she reaches out for the credstick makes him think that she has at least one cyber arm.
